[ewg] Chelsio's T4 DB drop recovery patches for review

[Vipul Pandya]

Hi All,

 

I have added a patch-series in linux-next-cherry-picks directory.

 

This patch-series is already merged with linux-next. However it is too
big to go into stable branch. It is required for Chelsio's T4 adapter
correctness. Hence adding patches to linux-next-cherry-picks.

 

The patch series is available at following location.

beany.openfabrics.org:/home/vipulp/new_ofed/compat-rdma

 

Kindly review them and let me know if it's appropriate for
linux-next-cherry-picks.

 

Thanks,

Vipul.

    linux-next-cherry-picks: Add DB drop recovery patches for Chelsio's
T4 adapter

 

    This patch-series implements doorbell drop recovery for Chelsio T4
iWARP driver.

 

    In the event where DBs are dropped application can get stalled for
one or more

    reasons. So, we recover RDMA and LLD queues in such an event.

    We also take care for handling DB overflow events.

 

    The patch-series also has some bug fixes, adds RDMA debugfs stats
and removes

    kfifo usage for ID mangement.

 

    This patch-series is already merged with linux-next. However it is
too big to

    go into stable branch. It is required for Chelsio's T4 adapter
correctness.

    Hence adding them to linux-next-cherry-picks.
