Subject: [PATCHv6 net-next 00/31] Misc. fixes for cxgb4 and iw_cxgb4

Hi All,

This patch series provides miscelleneous fixes for Chelsio T4/T5 adapters
related to cxgb4 related to sge and mtu. And includes DB Drop avoidance
and other misc. fixes on iw-cxgb4.

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

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

V6:
   In patch 8/31, move the existing neigh_release() call right before the
   if(!e) test, that way you don't need a completely new label and code block
   to fix this bug - thanks to review by David Miller
   In patch 15/31, use %pad to print dma_addr - thanks to review by Joe Perches
   In patch 10/31, add the "STOPPED" state string to db_state_str - thanks
   to review by Steve Wise
   In patch 10/31, t4_db_dropped() needs to disable dbs and send DB_FULL
   event to iw_cxgb4 - thanks to review by Steve Wise
V5:
   Dropped patch "cxgb4: use spinlock_irqsave/spinlock_irqrestore for db lock".
   The remaining changes from the removed patch are moved into patch 10/31
   ("Doorbell Drop Avoidance Bug Fixes").  10/31 has the driver call
   disable_txq_db() from an interrupt handler, and I thought it would be
   better to put all the changes to fix how the db lock is acquired into
   this one patch.   
   save/restore spinlock variants are not required - thanks to review by
   David Miller.
V4:
   Fixed review comments given by Sergei Shtylyov, Joe Perches, Or Gerlitz.
   And, dropped un-used module_params based on comment from Ben Hutchings.
   Also adds a new patch ("cxgb4: Calculate len properly for LSO
   path") which fixes regression.
V3:
   Fixed warnings reported by checkpatch.pl --strict & use networking code
   multi-line comments. Also includes fixes based on review comments given by
   Sergei Shtylyov.
V2:
   Dont drop existing module parameters.
