Subject: [PATCH net] ionic: account for vlan tag len in rx buffer len
Date: Fri, 18 Dec 2020 13:50:01 -0800
Message-ID: <20201218215001.64696-1-snelson@pensando.io> (raw)

Let the FW know we have enough receive buffer space for the
vlan tag if it isn't stripped.

Fixes: 0f3154e6bcb3 ("ionic: Add Tx and Rx handling")
