2017-06-29IB/opa_vnic: Use spinlock instead of mutex for stats_lockVishwanathapura, Niranjana1-4/+4
Stats can be read from atomic context, hence make stats_lock as a spinlock. Fix the following trace with debug kernel.

2017-04-20IB/opa-vnic: VNIC Ethernet Management Agent (VEMA) functionVishwanathapura, Niranjana1-1/+1
OPA VEMA function interfaces with the Infiniband MAD stack to exchange the management information packets with the Ethernet Manager (EM). It interfaces with the OPA VNIC netdev function to SET/GET the management information. The information exchanged with the EM includes class port details, encapsulation configuration, various counters, unicast and multicast MAC list and the MAC table. It also supports sending traps to the EM.

2017-04-20IB/opa-vnic: VNIC Ethernet Management Agent (VEMA) interfaceVishwanathapura, Niranjana1-0/+390
OPA VNIC EMA interface functions are the management interfaces to the OPA VNIC netdev. Add support to add and remove VNIC ports. Implement the required GET/SET management interface functions and processing of new management information. Add support to send trap notifications upon various events like interface status change, unicast/multicast mac list update and mac address change.
