cxgb4: Add CLIP support to store compressed IPv6 address
The Compressed LIP region is used to hold a limited number of Local
IPv6 addresses. This region is primarily used to reduce the TCAM
space consumed for an IPv6 offloaded connection. A 128-bit LIP will
be reduced to 13-bit and stored in the TCAM if there is a match
between the IPv6 tuple's LIP and the one stored in the CLIP region.
