From 0ca2b46dbb645c1aa23eda6f5ac49a7be31ac87d Mon Sep 17 00:00:00 2001 From: Jon Cooper Date: Wed, 8 Feb 2017 16:51:33 +0000 Subject: sfc: call mcdi_reboot_detected() when MC reboots during an MCDI command This function wasn't being called in this particular case when the MC reboots. This caused resource reallocations to not be handled properly and often ended up disabling the interface. Signed-off-by: Edward Cree Signed-off-by: David S.
