Steve Wise 24d44a391f RDMA/cma: Add IPv6 support for iWARP
Modify the type of local_addr and remote_addr fields in struct
iw_cm_id from struct sockaddr_in to struct sockaddr_storage to hold
IPv6 and IPv4 addresses uniformly.

Change the references of local_addr and remote_addr in cxgb4, cxgb3,
nes and amso drivers to match this.  However to be able to actully run
traffic over IPv6, low-level drivers have to add code to support this.

Roland Dreier d0c49bf391 RDMA/iwcm: Get rid of enum iw_cm_event_status
The IW_CM_EVENT_STATUS_xxx values were used in only a couple of places;
cma.c uses -Exxx values instead, and so do the amso1100, cxgb3 and cxgb4
drivers -- only nes was using the enum values (with the mild consequence
that all nes connection failures were treated as generic errors rather
than reported as timeouts or rejections).

We can fix this confusion by getting rid of enum iw_cm_event_status and
using a plain int for struct iw_cm_event.status, and converting nes to
use -Exxx as the other iWARP drivers do.

This also gets rid of the warning

Tom Tucker 922a8e9fb2 RDMA: iWARP Connection Manager.
Add an iWARP Connection Manager (CM), which abstracts connection
management for iWARP devices (RNICs).  It is a logical instance of the
xx_cm where xx is the transport type (ib or iw).  The symbols exported
are used by the transport independent rdma_cm module, and are
available also for transport dependent ULPs.
