Subject: [PATCH V2,net-next, 0/3] net: mana: Add support for EQ sharing

The existing code uses (1 + #vPorts * #Queues) MSIXs, which may exceed
the device limit.

Support EQ sharing, so that multiple vPorts can share the same set of
MSIXs.

Haiyang Zhang (3):
  net: mana: Move NAPI from EQ to CQ
  net: mana: Add support for EQ sharing
  net: mana: Add WARN_ON_ONCE in case of CQE read overflow
