2019-05-04i40e: Use struct_size() in kzalloc()Gustavo A. R. Silva1-4/+2
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; size = sizeof(struct foo) + count * sizeof(struct boo); instance = kzalloc(size, GFP_KERNEL) Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL) Notice that, in this case, variable size is not necessary, hence it is removed.

2019-05-04ice: Use bitfields where possibleJesse Brandeburg1-5/+5
The driver was converted to not use bool, but it was neglected that the bools should have been converted to bit fields as bit fields in software structures are ok, as long as they use the correct kinds of unsigned types. This avoids wasting lots of storage space to store single bit values. One of the change hunks moves a variable lport out of a group of "combinable" bit fields because all bits of the u8 lport are valid and the variable can be packed in the struct in struct holes.

2019-05-04ice: Refactor getting/setting coalesceBrett Creeley1-59/+93
Currently if the driver has an uneven amount of Rx/Tx queues setting the coalesce settings through ethtool will result in an error. This is happening because in the setting coalesce flow we are reporting an error if either Rx or Tx fails. Also, the flow for setting/getting per_q_coalesce and setting/getting coalesce settings for the entire device is different. Fix these issues by adding one function, ice_set_q_coalesce(), and another, ice_get_q_coalesce(), that both getting/setting per_q and entire device coalesce can use. This makes handling the error cases generic between the two flows and simplifies __ice_set_coalesce() and __ice_get_coalesce(). Also, add a header comment to __ice_set_coalesce().

However, we don't do this during the reset and VSI rebuild flow. This is inconsistent and unnecessary to have a difference between the two flows.

2019-05-04net: phy: improve resuming from hibernationHeiner Kallweit1-6/+1
I got an interesting report [0] that after resuming from hibernation the link has 100Mbps instead of 1Gbps. Reason is that another OS has been used whilst Linux was hibernated. And this OS speeds down the link due to WoL. Therefore, when resuming, we shouldn't expect that what the PHY advertises is what it did when hibernating. Easiest way to do this is removing state PHY_RESUMING. Instead always go via PHY_UP that configures PHY advertisement.

2019-05-04net: phy: improve pause handlingHeiner Kallweit3-9/+31
When probing the phy device we set sym and asym pause in the "supported" bitmap (unless the PHY tells us otherwise). However we don't know yet whether the MAC supports pause. Simply copying phy->supported to phy->advertising will trigger advertising pause, and that's not what we want. Therefore add phy_advertise_supported() that copies all modes but doesn't touch the pause bits. In phy_support_(a)sym_pause we shouldn't set any bits in the supported bitmap because we may set a bit the PHY intentionally disabled. Effective pause support should be the AND-combined PHY and MAC pause capabilities. If the MAC supports everything, then it's only relevant what the PHY supports. If MAC supports sym pause only, then we have to clear the asym bit in phydev->supported. Copy the pause flags only and don't touch the modes, because a driver may have intentionally removed a mode from phydev->advertising.

Anirudh introduces the framework to store queue specific information in the VSI queue contexts. This will allow future changes to update the structure to hold queue specific information. Akeem adds additional check so that if there is no queue to disable when attempting to disable a queue, return a configuration error without acquiring the lock. Fixed an issue with non-trusted VFs being able to add more than the permitted number of VLANs. Bruce removes unreachable code and updated the function to return void since it would never return anything but success. Brett provides most of the changes in the series, starting with reducing the scope of the error variable used and improved the debug message if we fail to configure the receive queue. Updates the driver to use a macro instead of using the same 'for' loop throughout the driver which helps with readability. Fixed an issue where users were led to believe they could set rx-usecs-high value, yet the changes to this value would not stick because it was not yet implemented to allow changes to this value, so implement the missing code to change the value. Found we had unnecessary wait when disabling queues, so remove it. I,proved a wasteful addition operation in our hot path by adding a member to the ice_q_vector structure and the necessary changes to use the member which stores the calculated vector hardware index. Refactored the link event flow to make it cleaner and more clear. Maciej updates the array index when stopping transmit rings, so that process every ring the VSI, not just the rings in a given transmit class. Paul adds support for setting 52 byte RSS hash keys. Md Fahad cleaned up a runtime change to the PFINT_OICR_ENA register, since the interrupt handlers will handle resetting the bit, if necessary.

The NULL pointer check of dev in ipheth_carrier_set() is therefore unnecessary and can be removed. Cc: Gustavo A. R.

2019-05-03net: dsa :mv88e6xxx: Disable unused portsAndrew Lunn1-1/+11
If the NO_CPU strap is set, the switch starts in 'dumb hub' mode, with all ports enable. Ports which are then actively used are reconfigured as required when the driver starts. However unused ports are left alone. Change this to disable them, and turn off any SERDES interface. This could save some power and so reduce the temperature a bit.

2019-05-03i40e: Introduce recovery mode supportAlice Michael3-31/+294
This patch introduces "recovery mode" to the i40e driver. It is part of a new Any2Any idea of upgrading the firmware. In this approach, it is required for the driver to have support for "transition firmware", that is used for migrating from structured to flat firmware image. In this new, very basic mode, i40e driver must be able to handle particular IOCTL calls from the NVM Update Tool and run a small set of AQ commands. These additional AQ commands are part of the interface used by the NVMUpdate tool. The NVMUpdate tool contains all of the necessary logic to reference these new AQ commands. The end user experience remains the same, they are using the NVMUpdate tool to update the NVM contents.

2019-05-03i40e: print PCI vendor and device ID during probeStefan Assmann1-3/+4
Printing each devices PCI vendor and device ID has the advantage of easily revealing what hardware we're dealing with exactly. It's no longer necessary to match the PCI bus information to the lspci output. Helps with bug reports where no lspci output is available.

2019-05-03i40e: fix misleading message about promisc setting on un-trusted VFHarshitha Ramamurthy1-12/+16
A refactor of the i40e_vc_config_promiscuous_mode_msg function moved the check for un-trusted VF into another function. We have to lie to an un-trusted VF that its request to set promiscuous mode is successful even when it is not because we don't want the VF to find out its trust status this way. With the refactor, we were running into a case where even though we were not setting promiscuous mode for an un-trusted VF, we still printed a misleading message that it was successful. This patch fixes that by ensuring that a success message is printed on the host side only when the promiscuous mode change has been successful.

2019-05-03i40e: remove out-of-range comparisons in i40e_validate_cloud_filterJacob Keller1-2/+2
The function i40e_validate_cloud_filter checks that the destination and source port numbers are valid by attempting to ensure that the number is non-zero and no larger than 0xFFFF. However, the types for the dst_port and src_port variable are __be16 which by definition cannot be larger than 0xFFFF Since these values cannot be larger than 2 bytes, the check to see if they exceed 0xFFFF is meaningless. One might consider these checks as some sort of defensive coding, in case the type was later changed. However, these checks also byte-swap the value before comparison using be16_to_cpu, which will truncate the values to 16bits anyways. Additionally, changing the type would require updating the opcodes to support new data layout of these virtchnl commands. Remove the check to silence the -Wtype-limits warning that was added to GCC 8.
