[PATCH 0/5] Misc. fix for cxgb4 and iw_cxgb4

[Hariprasad Shenai]

Hi,
This patch series adds support to enchance error reporting, log detailed
warning for negative advice, support query_qp verb and advertise correct
device max attributes for iwarp.

The patches series is created against 'net-next' tree.
And includes patches on cxgb4 and iw_cxgb4 driver.

Since this patch-series contains changes which are dependent on commit id
4c2c5763 ("cxgb4/iw_cxgb4: use firmware ord/ird resource limits") of net-next
tree we would like to request this patch series to get merged via David Miller's
'net-next' tree.

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

Thanks 

Hariprasad Shenai (5):
  cxgb4: Add the MC1 registers to read in the interrupt handler
  iw_cxgb4: log detailed warnings for negative advice
  iw_cxgb4: Support query_qp() verb
  iw_cxgb4: advertise the correct device max attributes
  iw_cxgb4: Don't limit TPTE count to 32KB

[PATCH 4/5] iw_cxgb4: advertise the correct device max attributes

[Hariprasad Shenai]

Advertise the actual max limits for things like qp depths, number of
qps, cqs, etc.

Clean up the queue allocation for qps and cqs.
