Merge branch 'cxgb4-next'

Hariprasad Shenai says:

====================
cxgb4: Use new BAR2 GTS for T5, adds adaptive rx and few Device ID's

This patch series adds support to use new BAR2 GTS for T5 adapter.
Adds support for adaptive rx. Remove redundant variable from a macro of
cxgb4vf driver. Adds Device ID for new adapters.

The patches series is created against 'net-next' tree.
And includes patches on cxgb4 and cxgb4vf driver.

We have included all the maintainers of respective drivers. Kindly review the
change and let us know in case of any review comments.
====================
