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

For the tid info, differentiate from which region the TID is allocated
from. It can be from TCAM region or HASH region.

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.
