ionic: use offset for ethtool regs data

2020-07-29T08:19:44Z

[ Upstream commit f85ae16f924f92a370b81b4e77862c1c59882fce ] 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.

ionic: centralize queue reset code

2020-07-16T06:13:23Z

[ Upstream commit 086c18f2452d0028f81e319f098bcb8e53133dbf ] 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.

ionic: print data for unknown xcvr type

2020-03-18T04:18:25Z

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.

ionic: drop ethtool driver version

2020-03-10T02:34:04Z

Use the default kernel version in ethtool drv_info output and drop the module version. Cc: Leon Romanovsky Signed-off-by: Shannon Nelson Reviewed-by: Leon Romanovsky Signed-off-by: David S. Miller

ionic: clean up bitflag usage

2020-03-10T02:34:04Z

Remove the unused flags field and and fix the bitflag names to include the _F_ flag hint. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: let core reject the unsupported coalescing parameters

2020-03-05T20:12:35Z

Set ethtool_ops->supported_coalesce_params to let the core reject unsupported coalescing parameters. This driver correctly rejects all unsupported parameters. As a side effect of these changes the error code for unsupported params changes from EINVAL to EOPNOTSUPP. v3: adjust commit message for new error code and member name Signed-off-by: Jakub Kicinski Acked-by: Shannon Nelson Signed-off-by: David S.

ionic: implement ethtool set-fec

2019-10-02T15:55:12Z

Wire up the --set-fec and --show-fec features in the ethtool callbacks and pull the related code out of set_link_ksettings. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: report users coalesce request

2019-10-02T15:55:12Z

The user's request for an interrupt coalescing value gets translated into a hardware value to be used with the NIC, and was getting reported back based on the hw value, which, due to hw tic resolution, could be reported as a different number than what the user originally asked for. This code now tracks both the user request and what was put into the hardware so we can report back to the user what they requested. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: use wait_on_bit_lock() rather than open code
