It doesn't look like it's loading the firmware.  Are there any obvious firmware-
loading errors in dmesg ?  If not, it might be worth installing  `sys-apps/lshw`
and running `lshw -C network` to see kernel resource information  regarding  the
device.

That looks fine, although why are you using such an outdated version of the
microcode ? For kernels 2.6.38+, you can use 8.83.5.1-1.

Perhaps it would be better to  install  it  from  the  Gentoo-provided  firmware
package ?  Amend /etc/portage/savedconfig/sys-kernel/linux-firmware  to  include
the appropriate entries (listing at [1]), and emerge `linux-firmware`  with  the
`savedconfig` USE-flag.
