Status in linux-firmware package in Ubuntu:

Bug description:
  Stock ubuntu 14.04 install, updated to the latest packages. Still
  seeing:

  root@ceph-eng-osd-walter:~# dmesg | grep cxgb4

  however:

  root@ceph-eng-osd-walter:~# ls -las /lib/firmware/cxgb4

  and the module is looking for it there also:

  root@ceph-eng-osd-walter:~# modinfo cxgb4 | grep firmware
  firmware:       cxgb4/t5fw.bin
  firmware:       cxgb4/t4fw.bin
  root@ceph-eng-osd-walter:~# 

  here's update-initramfs:
