Commit 101e63b4 authored by David S. Miller's avatar David S. Miller

Merge branch 'cxgb4-next'

Hariprasad Shenai says:

====================
cxgb4: minor fixes, decode msgs and code refactor for few functions

This patch series adds new routine to get adapter information and removes
some redundant messages logged in dmesg. Fixes race while freeing tx
descriptors. Decodes module type and link down reason codes obtained from
firmware. Refactor port initialization and FW_PORT_CMD handling. Pass
correct port id in DCB message handler to obtain netdev associated.

This patch series has been created against net-next tree and includes
patches on cxgb4 driver.

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