====================
cxgb4i: Add ipv6 support

   The following patchset add ipv6 support for the cxgb4i(iscsi) driver.

Patch 1 moves a define from the iw_cxgb4 to cxgb4 to prevent code duplication,
 as it is used by cxgb4i and iw_cxgb4 both.
Patch 2 exports symbols needed by cxgb4i for ipv6 support from cxgb4.
Patch 3 & 4 deal with actual ipv6 code in libcxgbi/cxgb4i.

Submitting to net-next as changes were needed in cxgb4/iw_cxgb4, and submitting
to scsi separately would break compilation, cc-ing scsi & rdma.

v2 : Cleanup macro that prints ip addresses by using %pIS in patch 3
