Firmware required by bna is stored in appropriate files as sequence of LE32 integers. After loading by request_firmware() they need to be byte-swapped on big-endian arches. Without this conversion the NIC is unusable on big-endian machines. Cc: Rasesh Mody <rasesh.mody@qlogic.com> Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S.
