This patch series creates RNIC adapter in mana_ib.
To create the adapter, we must create one EQ.
In the future patches, this EQ will be used for fatal RC QP error events.
In the future patches, we will also add more EQs for CQs.

mana_ib is served by mana ethernet for RAW QPs and by RNIC for RC QPs.
If RNIC is not available in the HW, we do not fail mana_ib and keep only RAW QP
support. RNIC is availale only for port 1.

As a minimal usage, this patch series brings adding and removing RoCEv2 GIDs.
For this, we set master netdev to the ib device and set required port parameters
to get GIDs. RNIC of mana supports IPv6 and IPv4 addresses that are stored in the HW.

v1->v2:
* Fixed rcu_read_unlock() and updated commit message in "Enable RoCE on port 1"
