Subject[PATCH 5.4 159/191] bnxt_en: Free context memory in the open path if firmware has been reset.
Date
From: Michael Chan <michael.chan@broadcom.com>

[ Upstream commit 325f85f37e5b35807d86185bdf2c64d2980c44ba ]

This will trigger new context memory to be rediscovered and allocated
during the re-probe process after a firmware reset. Without this, the
newly reset firmware does not have valid context memory and the driver
will eventually fail to allocate some resources.

Fixes: ec5d31e3c15d ("bnxt_en: Handle firmware reset status during IF_UP.")
