Subject: [PATCH net 2/4] be2net: Fix ethtool get drvinfo
From: Kalesh AP <kalesh.purayil@...lex.com>
Cannot issue any other mailbox command while firmware download is in progress.
The get_drvinfo ethtool hook can be invoked without acquiring any rtnl_lock.
So removing the be_get_fw_ver query from be_get_drvinfo ethtool hook as it times
out during firmware download.
