This is fixed in RHEL6.3 (beta) where the kernel-firmware package 
contains the latest firmware that you are missing above:

$ rpm -q kernel-firmware
kernel-firmware-2.6.32-262.el6.noarch
$ rpm -ql kernel-firmware | grep bnx2-mips
/lib/firmware/bnx2/bnx2-mips-06-5.0.0.j6.fw
/lib/firmware/bnx2/bnx2-mips-06-6.0.15.fw
/lib/firmware/bnx2/bnx2-mips-06-6.2.1.fw
/lib/firmware/bnx2/bnx2-mips-06-6.2.3.fw
/lib/firmware/bnx2/bnx2-mips-09-5.0.0.j15.fw
/lib/firmware/bnx2/bnx2-mips-09-5.0.0.j3.fw
/lib/firmware/bnx2/bnx2-mips-09-6.0.17.fw
/lib/firmware/bnx2/bnx2-mips-09-6.2.1a.fw
/lib/firmware/bnx2/bnx2-mips-09-6.2.1b.fw

In the meantime (as a workaround), just grab the missing firmware and 
place it in the appropriate directory.
