This file fails to load for me:
thost kernel: [ T2503] r8152 1-3:1.0: unused bp5 is not zero
thost kernel: [ T2503] r8152 1-3:1.0: check USB firmware failed
thost kernel: [ T2503] r8152 1-3:1.0: unable to load firmware patch rtl_nic/rtl8153a-4.fw (-14)

Looking at the above file it has fw_mac->bp_num set to 5,
but fw_mac->bp[] array has 6 elements filled.

If I force fw_mac->bp_num to 6 in the code it loads successfully,
so perhaps it's a mistake in the firmware header?
