2013-04-19net: vlan: add protocol argument to packet tagging functionsPatrick McHardy1-1/+1
Add a protocol argument to the VLAN packet tagging functions. In case of HW tagging, we need that protocol available in the ndo_start_xmit functions, so it is stored in a new field in the skb. The new field fits into a hole (on 64 bit) and doesn't increase the sks's size. Signed-off-by: Patrick McHardy <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2013-04-19net: vlan: prepare for 802.1ad VLAN filtering offloadPatrick McHardy1-3/+5
Change the rx_{add,kill}_vid callbacks to take a protocol argument in preparation of 802.1ad support. The protocol argument used so far is always htons(ETH_P_8021Q). Signed-off-by: Patrick McHardy <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2013-04-19net: vlan: rename NETIF_F_HW_VLAN_* feature flags to NETIF_F_HW_VLAN_CTAG_*Patrick McHardy1-3/+3
Rename the hardware VLAN acceleration features to include "CTAG" to indicate that they only support CTAGs. Follow up patches will introduce 802.1ad server provider tagging (STAGs) and require the distinction for hardware not supporting acclerating both.

2013-02-15igbvf: Make next_to_watch a pointer and adjust memory barriers to avoid racesAlexander Duyck1-22/+30
This change is meant to address several race issues that become possible because next_to_watch could possibly be set to a value that shows that the descriptor is done when it is not. In order to correct that we instead make next_to_watch a pointer that is set to NULL during cleanup, and set to the eop_desc after the descriptor rings have been written. To enforce proper ordering the next_to_watch pointer is not set until after a wmb writing the values to the last descriptor in a transmit. In order to guarantee that the descriptor is not read until after the eop_desc we use the read_barrier_depends which is only really necessary on the alpha architecture.

2013-02-04ethernet: Remove unnecessary alloc/OOM messages, alloc cleanupsJoe Perches1-5/+3
alloc failures already get standardized OOM messages and a dump_stack. Convert kzalloc's with multiplies to kcalloc. Convert kmalloc's with multiplies to kmalloc_array. Fix a few whitespace defects. Convert a constant 6 to ETH_ALEN. Use parentheses around sizeof. Convert vmalloc/memset to vzalloc. Remove now unused size variables.

2013-01-28igbvf: be sane about random MAC addressesMitch A Williams1-14/+10
Tighten up some of the code surrounding MAC addresses. Since the PF is now giving all zeros instead of a random address, check for this case and generate a random address. This ensures that we always know when we have a random address and udev won't get upset about it. Additionally, tighten up some of the log messages and clean up the formatting.

2012-12-07drivers/net: fix up function prototypes after __dev* removalsGreg Kroah-Hartman1-2/+1

2012-02-13rename dev_hw_addr_random and remove redundant secondDanny Kukawka1-4/+7
Renamed dev_hw_addr_random to eth_hw_addr_random() to reflect that this function only assign a random ethernet address (MAC). Removed the second parameter (u8 *hwaddr), it's redundant since the also given net_device already contains net_device->dev_addr. Set it directly. Adapt igbvf and ixgbevf to the changed function. Small fix for ixgbevf_probe(): if ixgbevf_sw_init() fails (which means the device got no dev_addr) handle the error and jump to err_sw_init as already done by igbvf in similar case.

2012-02-07igbvf: refactor Interrupt Throttle Rate codeMitch A Williams1-57/+74
The existing ITR code is broken and confusing, with lots of similarly-named variables that do different things. Additionally, after the driver carefully determines the optimal interrupt rate for the adapter, it then ignores it and always writes a fixed, suboptimal value. This patch refactors that code to make variable names more descriptive of what they actually do, and then actually writes the calculated result to the hardware. Preliminary testing shows that netperf TCP_STREAM tests goes from ~918Mbps to ~940Mbps, and TCP_RR goes from ~2k transactions/sec up to > 8k.
