drivers: net: ionic: simplify the return expression of ionic_set_rxfh()

2020-12-09T00:22:54Z

Simplify the return expression. Signed-off-by: Zheng Yongjun Signed-off-by: David S. Miller

ionic: check port ptr before use

2020-11-05T17:58:25Z

Check for corner case of port_init failure before using the port_info pointer. Fixes: 4d03e00a2140 ("ionic: Add initial ethtool support") Signed-off-by: Shannon Nelson Link: https://lore.kernel.org/r/20201104195606.61184-1-snelson@pensando.io Signed-off-by: Jakub Kicinski

ionic: dynamic interrupt moderation

2020-09-17T00:35:47Z

Use the dim library to manage dynamic interrupt moderation in ionic. v3: rebase v2: untangled declarations in ionic_dim_work() Signed-off-by: Shannon Nelson Acked-by: Jakub Kicinski Signed-off-by: David S. Miller

ionic: clarify boolean precedence

2020-09-02T22:47:01Z

Add parenthesis to clarify a boolean usage. Pointed out in https://lore.kernel.org/lkml/202008060413.VgrMuqLJ%25lkp@intel.com/ Reported-by: kernel test robot Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: change queue count with no reset

2020-08-28T15:01:30Z

Add to our new ionic_reconfigure_queues() to also be able to change the number of queues in use, and to change the queue interrupt layout between split and combined. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: change the descriptor ring length without full reset

2020-08-28T15:01:30Z

The original way of changing ring length was to completely tear down the lif's queue structure and then rebuild it, while running the risk of allocations that might fail in the middle and leave us with a broken driver. Instead, we can set up all the new queue and descriptor allocations first, then swap them out and delete the old allocations. If the new allocations fail, we report the error, stay with the old setup and continue running. This gives us a safer path, and a smaller window of time where we're not processing traffic.

ionic: rework and simplify handling of the queue stats block

2020-08-28T15:01:30Z

Use a block of stats structs attached to the lif instead of little ones attached to each qcq. This simplifies our memory management and gets rid of a lot of unnecessary indirection. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: separate interrupt for Tx and Rx

2020-08-03T22:32:02Z

Add the capability to split the Tx queues onto their own interrupts with their own napi contexts. This gives the opportunity for more direct control of Tx interrupt handling, such as CPU affinity and interrupt coalescing, useful for some traffic loads. v2: use ethtool -L, not a vendor specific priv-flag v3: simplify logging, drop unnecessary "no-change" tests Reviewed-by: Jakub Kicinski Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: use offset for ethtool regs data

2020-07-21T01:09:38Z

Use an offset to write the second half of the regs data into the second half of the buffer instead of overwriting the first half. Fixes: 4d03e00a2140 ("ionic: Add initial ethtool support") Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: centralize queue reset code

2020-07-07T22:50:31Z

The queue reset pattern is used in a couple different places, only slightly different from each other, and could cause issues if one gets changed and the other didn't. This puts them together so that only one version is needed, yet each can have slighty different effects by passing in a pointer to a work function to do whatever configuration twiddling is needed in the middle of the reset. This specifically addresses issues seen where under loops of changing ring size or queue count parameters we could occasionally bump into the netdev watchdog. v2: added more commit message commentary Fixes: 4d03e00a2140 ("ionic: Add initial ethtool support") Signed-off-by: Shannon Nelson Acked-by: Jakub Kicinski Signed-off-by: David S.
