2020-03-15net: qlnic: let core reject the unsupported coalescing parametersJakub Kicinski1-18/+5
Set ethtool_ops->supported_coalesce_params to let the core reject unsupported coalescing parameters. This driver already correctly rejected almost all unsupported parameters (missing sample_rate_interval). As a side effect of these changes the error code for unsupported params changes from EINVAL to EOPNOTSUPP. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2017-05-12qlcnic: Fix link configuration with autoneg disabledChopra, Manish1-0/+3
Currently driver returns error on speed configurations for 83xx adapter's non XGBE ports, due to this link doesn't come up on the ports using 1000Base-T as a connector with autoneg disabled. This patch fixes this with initializing appropriate port type based on queried module/connector types from hardware before any speed/autoneg configuration.

2016-03-11qlcnic: Fix mailbox completion handling during spurious interruptRajesh Borundia1-1/+2
o While the driver is in the middle of a MB completion processing and it receives a spurious MB interrupt, it is mistaken as a good MB completion interrupt leading to premature completion of the next MB request. Fix the driver to guard against this by checking the current state of MB processing and ignore the spurious interrupt. Also added a stats counter to record this condition.

2014-09-26qlcnic: Fix ordering of stats in stats buffer.Manish Chopra1-0/+2
o When TX queues are not allocated, driver does not fill TX queues stats in the buffer. However, it is also not advancing data pointer by TX queue stats length, which would misplace all successive stats data in the buffer and will result in mismatch between stats strings and it's values. o Fix this by advancing data pointer by TX queue stats length when queues are not allocated.

2014-09-26qlcnic: Fix memory corruption while reading stats using ethtool.Manish Chopra1-4/+2
o Driver is doing memset with zero for total number of stats bytes when it has already filled some data in the stats buffer, which can overwrite memory area beyond the length of stats buffer. o Fix this by initializing stats buffer with zero before filling any data in it.

o Aggregating tx stats in adapter variable was resulting in an increase in stats even after no traffic was run and user runs ifconfig/ethtool command. o qlcnic_update_stats used to accumulate stats in adapter struct at each function call, instead accumulate tx stats in local variable and then assign it to adapter structure.
