2015-04-03i40e: fix invalid void return in FCoE codeJesse Brandeburg1-2/+1
A function was calling i40e_tx_map with return, but tx_map returns void, and the caller returns void, so just drop the return, and everything is good.

2015-04-03i40e/i40evf: fix bug when skb allocation failsJesse Brandeburg1-1/+4

2015-03-09i40e: tame the nvmupdate read and write complaintsShannon Nelson1-2/+7
The NVMUpdate tool doesn't necessarily know the ReadOnly map of the current NVM image, and must try reading and writing words that may be protected. This generates an error out of the Firmware request that the driver logs. Unfortunately, this ends up spitting out hundreds of bogus read and write error message that looks rather messy. This patch checks the error type and under normal conditions will not print the typical read and write errors during NVMUpdate. This can be overridden by enabling the NVM update debugging. This results in a much less messy log file, and likely many fewer customer support questions.

2015-03-07i40e: FD filters flush policy changesAnjali Singhai Jain3-20/+67
Since GLQF_FDCNT_0 register now has the right offset, use it to simplify our FD flush flow. If the filter add error happens to be for SB we just auto disable SB. If filter error happens to be for ATR, auto disable ATR and mark the state to FD_FLUSH_REQUESTED. Which gets cleared when flush completes. If we are entering flush too quickly (< 30 seconds) and we have quite a few SB rules, its time to disable ATR for good. Since SB + ATR rules is most likely making the FD table unstable. ATR can be re-enabled by turning ntuple off (ethtool -K ntuple off) and will remain off after turning ntuple on till it gets unstable again.

2015-03-07i40e: rework vector reservationShannon Nelson1-19/+56
The initial problem solved here is that the vector allocation was trying too hard to save vectors for VMDq, to the point of not giving the PF enough when in a tight situation such as an NPAR partition. This change makes sure that the PF will get all the queues and vectors it wants to fill out its destiny. Essentially, nothing is specially reserved for VMDq, it simply gets whatever is left after the PF, FCoE, and FD sideband get what they want. Additionally, the calculations for the reservations were harder to follow than necessary, so I've made it more straight forward.

2015-03-05i40e: Fix NPAR Tx Scheduler initGreg Rose1-0/+4
Recent changes to the driver initialization have caused the BW configurations to not take effect. We use a BW configuration read and write back to "kick" the Tx scheduler into action.

Conflicts: drivers/net/ethernet/rocker/rocker.c The rocker commit was two overlapping changes, one to rename the ->vport member to ->pport, and another making the bitmask expression use '1ULL' instead of plain '1'. Signed-off-by: David S. Miller <davem@davemloft.net>

Matthew updates the fm10k driver by cleaning up code comments and whitespace issues. Also modifies the tunnel length header check, to make it more robust by calculating the inner L4 header length based on whether it is TCP or UDP. Implemented ndo_features_check() that allows drivers to report their offload capabilities per-skb. Neerav updates the i40e driver to skip over priority tagging if DCB is not enabled. Fixes an issue where the driver is not flushing out the DCBNL app table for applications that are not present in the local DCBX application configuration TLVs. Fixed i40e where, in the case of MFP mode, the driver was returning the incorrect number of traffic classes for partitions that are not enabled for iSCSI. Even though the driver was not configuring these traffic classes in the transmit scheduler for the NIC partitions, it does use this map to setup the queue mappings. Shannon updates i40e/i40evf to include the firmware build number in the formatted firmware version string. Akeem adds a safety net (by adding a 'default' case) for the possible unmatched switch calls. Mitch updates i40e to not automatically disable PF loopback at runtime, now that we have the functionality to enable and disable PF loopback. This fix cleans up a bogus error message when removing the PF module with VFs enabled. Adds a extra check to make sure that the indirection table pointer is valid before dereferencing it. Anjali enables i40e to enable more than the max RSS qps when running in a single TC mode for the main VSI. It is possible to enable as many as num_online_cpus(). Adds a firmware check to ensure that DCB is disabled for firmware versions older than 4.33. Updates i40e/i40evf to add missing packet types for VXLAN offload. Updated i40e to be able to handle varying RSS table size for each VSI, since all VSI's do not have the same RSS table size. v2: Dropped previous patch #9 "i40e/i40evf: Add capability to gather VEB per TC stats" since the stats should be in ethtool and not debugfs. ==================== Signed-off-by: David S.
