[dpdk-dev] [PATCH 3/4] net/sfc: make adapter lock recursive

[Andrew Rybchenko <andrew.rybchenko@oktetlabs.ru>]

Adapter lock is held when mempool for MAE counter packets is populated.
Follow up patch will add a callback on mempool creation which
requires to take lock as well. However, the callback will be called for
other mempools as well when adapter lock is not held.
