2021-10-24net: convert users of bitmap_foo() to linkmode_foo()Sean Anderson1-2/+1
This converts instances of bitmap_foo(args..., __ETHTOOL_LINK_MODE_MASK_NBITS) to linkmode_foo(args...) I manually fixed up some lines to prevent them from being excessively long.

2020-08-28ionic: change the descriptor ring length without full resetShannon Nelson1-9/+26
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.

2020-08-28ionic: rework and simplify handling of the queue stats blockShannon Nelson1-2/+2

2020-07-07ionic: centralize queue reset codeShannon Nelson1-35/+17
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 <snelson@pensando.io> Acked-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-05-12ionic: support longer tx sg listsShannon Nelson1-2/+2
The version 1 Tx queues can use longer SG lists than the original version 0 queues, but we need to check to see if the firmware supports the v1 Tx queues. This implements the queue type query for all queue types, and uses the information to set up for using the longer Tx SG lists. Because the Tx SG list can be longer, we need to limit the max ring length to be sure we stay inside the boundaries of a DMA allocation max size, so we lower the max Tx ring size. The driver sets its highest known version in the Q_IDENTITY command, and the FW returns the highest version that it knows, bounded by the driver's version. The negotiated version number is later used in the Q_INIT commands. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-17ionic: print data for unknown xcvr typeShannon Nelson1-4/+9
If we don't recognize the transceiver type, set the xcvr type and data length such that ethtool can at least print the first 256 bytes and the reader can figure out why the transceiver is not recognized. While we're here, we can update the phy_id type values to use the enum values in sfp.h.
