Íñigo Huguet says:
====================
sfc: fix some efx_separate_tx_channels errors
Trying to load sfc driver with modparam efx_separate_tx_channels=1
resulted in errors during initialization and not being able to use the
NIC. This patches fix a few bugs and make it work again.
v2:
* added Martin's patch instead of a previous mine. Mine one solved some
of the initialization errors, but Martin's solves them also in all
possible cases.
* removed whitespaces cleanup, as requested by Jakub
====================
