Subject: [PATCH net-next 08/14] sfc: remove duplicate declaration of
 efx_enqueue_skb_tso()

Define it in nic_common.h, even though the ef100 driver will have a
 different implementation backing it (actually a WARN_ON_ONCE as it
 should never get called by ef100.  But it needs to still exist because
 common TX path code references it).
