bnx2x: Prevent UDP 4-tuple configurations on older adapters

2015-10-11T12:09:30Z

Configuring 4-tuple RSS hsahing for UDP [E.g., by using `ethtool -N rx-flow-hash udp4 sdfn'] on a 57710/57711 adapter would cause it to assert as HW does not support such a configuration. Signed-off-by: Yuval Mintz Signed-off-by: Ariel Elior Signed-off-by: David S. Miller

bnx2x: byte swap rss_key to comply to Toeplitz specs

2015-09-24T21:34:49Z

After a good amount of debugging, I found bnx2x was byte swaping the 40 bytes of rss_key. If we byte swap the key, then bnx2x generates hashes matching MSDN specs as documented in (Verifying the RSS Hash Calculation) https://msdn.microsoft.com/en-us/library/windows/hardware/ff571021% 28v=vs.85%29.aspx It is mostly a non issue, unless we want to mix different NIC in a host, and want consistent hashing among all of them, ie if they all use the boot time generated rss key, or if some application is choosing specific tuple(s) so that incoming traffic lands into known rx queue(s).

bnx2x: track vxlan port count

2015-09-18T05:32:16Z

The callback for adding vxlan port can be called with the same port for both IPv4 and IPv6. Do not disable the offloading when the same port for both protocols is added and later one of them removed. Signed-off-by: Jiri Benc Signed-off-by: David S. Miller

bnx2x: use ktime_get_seconds() for timestamp

2015-09-11T22:02:59Z

commit c48f350ff5e7 "bnx2x: Add MFW dump support" added the bnx2x_update_mfw_dump() function that reads the current time and stores it in a 32-bit field that gets passed into a buffer in a fixed format. This is potentially broken when the epoch overflows in 2038, and otherwise overflows in 2106. As we're trying to avoid uses of struct timeval for this reason, I noticed the addition of this function, and tried to rewrite it in a way that is more explicit about the overflow and that will keep working once we deprecate struct timeval. I assume that it is not possible to change the ABI any more, otherwise we should try to use a 64-bit field for the seconds right away.

bnx2x: Fix vxlan endianity issue

2015-08-20T21:08:08Z

Commit f34fa14cc033 ("bnx2x: Add vxlan RSS support") has introduced an endianity issue when passing the vxlan UDP port to the HW. Reported-by: Signed-off-by: Yuval Mintz Signed-off-by: David S. Miller

bnx2x: Add vxlan RSS support

2015-08-18T21:21:10Z

Latest FW submission added some vxlan offload capabilities to our device. This patch adds the ability to connect to the vxlan NDOs and configure the UDP port associated with it in the HW. The device would now be capable of performing RSS according to the inner headers of the vxlan packets. Signed-off-by: Rajesh Borundia Signed-off-by: Yuval Mintz Signed-off-by: David S. Miller

bnx2: Fix bandwidth allocation for some MF modes

2015-08-17T17:27:57Z

Management firmware tells driver in case bandwidth configuration for a specific function exists, but [regretably] the same field has different meanings depending on the multi-function mode - it can either be a percentile value or an actual speed. For newer multi-function modes current logic is incorrect - driver understands values as actual speeds instead of percentages, causing the resulting chip configuration to be incorrect.

bnx2x: Free NVRAM lock at end of each page

2015-08-10T21:31:59Z

Writing each 4Kb page into flash might take up-to ~100 miliseconds, during which time management firmware cannot acces the nvram for its own uses. Firmware upgrade utility use the ethtool API to burn new flash images for the device via the ethtool API, doing so by writing several page-worth of data on each command. Such action might create problems for the management firmware, as the nvram might not be accessible for a long time. This patch changes the write implementation, releasing the nvram lock on the completion of each page, allowing the management firmware time to claim it and perform its own required actions.
