Bug#1006500: Missing bnx2x firmware 7.13.21.0 renders NIC unusable with Linux 5.16

[Shane St. Savage]

As someone who has bricked multiple servers and weekends trying to work
around this in an iPXE/preseed installer environment, I would also be very
appreciative of a backport release of 20220913-1~deb11u1 (assuming enough
settlement time has passed). Thanks for all your work on Debian!
