2012-02-10ixgbe: Add function for testing status bits in Rx descriptorAlexander Duyck3-55/+65
This change adds a small function for testing Rx status bits in the descriptor. The advantage to this is that we can avoid unnecessary byte swaps on big endian systems.

2012-02-10ixgbe: Let the Rx buffer allocation clear status bits instead of cleanupAlexander Duyck1-62/+93
This change makes it so that we always clear the status/error bits in the Rx descriptor in the allocation path instead of the cleanup path. The advantage to this is that we spend less time modifying data. As such we can modify the data once and then let it go cold in the cache instead of writing it, reading it, and then writing it again.

2012-02-10ixgbe: Address fact that RSC was not setting GSO size for incoming framesAlexander Duyck1-5/+125
This patch is meant to address the fact that RSC has not been setting the gso_size value on the skb. As a result performance on lossy TCP connections was negatively impacted. This change resolves the issue by setting gso_size to the average size for incoming packets.

2012-02-10ixgbe: Minor refactor of RSCAlexander Duyck2-98/+147
This change addresses several issue. First I had left the use of the next and prev skb pointers floating around in the code and they were overdue to be pulled since I had rewritten the RSC code in the out-of-tree driver some time ago to address issues brought up by David Miller in regards to this. I am also now defaulting to always leaving the first buffer unmapped on any packet and then unmapping it after we read the EOP descriptor. This allows a simplification of the path with less branching. Instead of counting packets received the code was changed some time ago to track the number of buffers received. This leads to inaccurate counting when you compare numbers of packets received by the hardware versus what is tracked by the software. To correct this I am revising things so that the append_cnt value for RSC accurately tracks the number of frames received.

2012-02-09ixgbe: ethtool: stats user buffer overrunJohn Fastabend1-37/+51
If the number of tx/rx queues changes the ethtool ioctl ETHTOOL_GSTATS may overrun the userspace buffer. This occurs because the general practice in user space to query stats is to issue a ETHTOOL_GSSET cmd to learn the buffer size needed, allocate the buffer, then call ETHTOOL_GSTIRNGS and ETHTOOL_GSTATS. If the number of real_num_queues is changed or flow control attributes are changed after ETHTOOL_GSSET but before the ETHTOOL_GSTRINGS/ETHTOOL_GSTATS a user space buffer overrun occurs. To fix the overrun always return the max buffer size needed from get_sset_count() then return all strings and stats from get_strings()/get_ethtool_stats(). This _will_ change the output from the ioctl() call which could break applications and script parsing in theory. I believe these changes should not break existing tools because the only changes will be more {tx|rx}_queues and the {tx|rx}_pb_* stats will always be returned. Existing scripts already need to handle changing number of queues because this occurs today depending on system and current features. The {tx|rx}_pb_* stats are at the end of the output and should be handled by scripts today regardless. Finally get_ethtool_stats and get_strings are free-form outputs tools parsing these outputs should be defensive anyways. In the end these updates are better then having a tool segfault because of a buffer overrun. Signed-off-by: John Fastabend <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]>
2012-02-09ixgbe: dcb: up2tc mapping lost on disable/enable CEE DCB stateJohn Fastabend1-2/+9
Users expect the up2tc mapping to be maintained across a DCB enable/disable/enable transition. And since we maintain all the other DCB attributes we should do this for up2tc mappings as well just to be consistent. Also without this we break user space applications that expect this to occur that previously worked.

2012-02-09ixgbe: do not update real num queues when netdev is going awayYi Zou1-0/+4
If the netdev is already in NETREG_UNREGISTERING/_UNREGISTERED state, do not update the real num tx queues. netdev_queue_update_kobjects() is already called via remove_queue_kobjects() at NETREG_UNREGISTERING time. So, when upper layer driver, e.g., FCoE protocol stack is monitoring the netdev event of NETDEV_UNREGISTER and calls back to LLD ndo_fcoe_disable() to remove extra queues allocated for FCoE, the associated txq sysfs kobjects are already removed, and trying to update the real num queues would cause something like below: ...

2012-02-09ixgbe: Fix broken dependency on MAX_SKB_FRAGS being related to page sizeAlexander Duyck1-6/+6
This patch fixes an issue in which RSC will generate corrupted frames when PAGE_SIZE is larger than 8K. Specifically it looks like that in 2.6.39 a change was made so that GRO would always have at least 16 frags available for coalescing, but the ixgbe RSC logic was not updated. As such the RSC feature would generate a frame larger than 64K and then overflow the value in the IP length field. To correct that I am now basing things on the PAGE_SIZE.

2011-12-05ixgbe: DCB: IEEE transitions may fail to reprogram hardware.John Fastabend1-11/+10
Transitioning through an IEEE DCBX version from a CEE DCBX and back (CEE->IEEE->CEE) may leave IEEE attributes programmed in the hardware. DCB uses a bit field in the set routines to determine which attributes PG, PFC, APP need to be reprogrammed. This is needed because user flow allows queueing a series of changes and then reprogramming the hardware with the entire set in one operation. When transitioning from IEEE DCBX mode back into CEE DCBX mode the PG and PFC bits need to be set so the possibly different CEE attributes get programmed into the device. This patch fixes broken logic that was evaluating to 0 and never setting any bits. Further this removes some checks for num_tc in set routines. This logic only worked when the number of traffic classes and user priorities were equal. This is no longer the case for X540 devices. Besides we can trust user input in this case if the device is incorrectly configured the DCB bandwidths will be incorrectly mapped but no OOPs, BUG, or hardware failure will occur.

ixgbe allocates half a page per skb fragment. We must account PAGE_SIZE/2 increments on skb->truesize, not the actual frag length. Signed-off-by: Eric Dumazet <[email protected]> CC: Jeff Kirsher <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2011-10-12ixgbe: Correct check for change in FCoE priorityMark Rustad1-2/+10
Correct a check for change in FCoE priority when IEEE mode DCB is in use. In IEEE mode a different function has to be used to get the FCoE priority mask. Also, the check for the mask assumed that only one priority was set. In case there should be more than one, check just the bit. These changes help avoid link flapping issues that can come up when IEEE DCB is in use.

2011-10-12ixgbe: Add FCoE DDP allocation failure counters to ethtool stats.Amir Hanania5-11/+56
Add 2 new counters to ethtool: 1. Count DDP allocation failure since we max the number of buffers allowed in one DDP context. 2. Count DDP allocation failure since we max the number of buffers allowed in one DDP context when we alloc an extra buffer.
