ionic: Prevent filter add/del err msgs when the device is not available
Currently when a request for add/deleting a filter is made when ionic_heartbeat_check() returns failure the driver will be overly verbose about failures, especially when these are usually temporary fails and the request will be retried later. An example of this is a filter add when the FW is in the middle of resetting: IONIC_CMD_RX_FILTER_ADD (31) failed: IONIC_RC_ERROR (-6) rx_filter add failed: ADDR 01:80:c2:00:00:0e Fix this by checking for -ENXIO and other error values on filter request fails before printing the error message. Add similar checking to the delete filter code. Fixes: f91958cc9622 ("ionic: tame the filter no space message") Signed-off-by: Brett Creeley <brett@pensando.io> Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S.
