Hi all,

Sorry for any confusion we may have caused. Our plan was for the qed series 
to be considered for net-next, and for the nvme-tcp-offload series to be 
considered for nvme mailing list.
We attempted to communicate this in the cover letter and the addresses 
in to: vs. those in cc:, but perhaps this was not clear enough.

The plan was detailed in the cover latter under the "upstream plan" section 
https://lore.kernel.org/netdev/20210531225222.16992-1-smalin@marvell.com/
The series is structured in a modular way so that part 1 (nvme-tcp-offload) 
and part 2 (qed) are independent and part 3 (qedn) depends on both parts 1+2.

We have sent the first 2 parts which are independent:

- QED NVMeTCP Offload - https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=eda1bc65b0dc1b03006e427430ba23746ec44714
  This part includes the qed infrastructure which was discussed over the RFC.
  Our intent for this part was for it to be accepted to net-next, which it was.
  Dave, from our perspective this piece can stay in net-next.

- NVMeTCP Offload ULP - https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=5ff5622ea1f16d535f1be4e478e712ef48fe183b
  This is the nvme-tcp-offload ULP which we intended the NVMe tree,
  and it shouldn't be merged to net-next.
  Dave, please revert this from net-next until nvme maintainers are completely 
  satisfied with it.

Christoph, we would be more than happy to incorporate any feedback you may 
provide for any part of the series.
