[PATCH net-next 0/4] Add some more debug info

[Hariprasad Shenai]

Hi,

This patch series adds the following.
Add more info for sge_qinfo dump
Differentiate tid and stids between different regions, and add a debugfs
entry to dump all the tid info

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.

Thanks

[PATCH net-next 3/4] cxgb4: Differentiate between stids between server and filter region

[Hariprasad Shenai]

For T4 adapter, offloaded servers tid for IPv4 connections are
allocated from filter region. So add a new field for server filter tid if
server tid is allocated from filter region.
