2016-10-04net/ncsi: Allow to extend NCSI request propertiesGavin Shan1-1/+1
There is only one NCSI request property for now: the response for the sent command need drive the workqueue or not. So we had one field (@driven) for the purpose. We lost the flexibility to extend NCSI request properties. This replaces @driven with @flags and @req_flags in NCSI request and NCSI command argument struct. Each bit of the newly introduced field can be used for one property. No functional changes introduced.

2016-07-19net/ncsi: NCSI command packet handlerGavin Shan1-0/+367
The NCSI command packets are sent from MC (Management Controller) to remote end. They are used for multiple purposes: probe existing NCSI package/channel, retrieve NCSI channel's capability, configure NCSI channel etc. This defines struct to represent NCSI command packets and introduces function ncsi_xmit_cmd(), which will be used to transmit NCSI command packet according to the request. The request is represented by struct ncsi_cmd_arg. Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Acked-by: Joel Stanley <joel@jms.id.au> Signed-off-by: David S. Miller <davem@davemloft.net>
