[dpdk-dev] [PATCH v2 04/62] common/sfc_efx/base: add MAE init/fini APIs

[Andrew Rybchenko]

From: Ivan Malov <ivan.malov at oktetlabs.ru>

The patch adds APIs for client drivers to initialise / finalise
MAE-specific context in NIC control structure. The context
itself will be used by the follow-up patches to store
supportive data for library-internal consumers.
