Hi I have had this issue with Dell R610s as well (inital install and after a EVE upgrade once).

The firmware you need is in another directory (probably /lib/firmware/bnx2x) and you need to copy it into the /lib/firmware/bnx2 directory (or create the directory first if it doesn't exist).

Cheers

thanks sipart,

problem solved after applying below commands.

cd /lib/firmware/bnx2x/
mkdir bnx2-mips-09-6.2.1b.fw
cp -i /lib/firmware/4.4.0-98-generic/bnx2/bnx2-mips-09-6.2.1b.fw /lib/firmware/bnx2/bnx2-mips-09-6.2.1b.fw
