Subject: [RFC 00/19] qed*: Add iWARP support for QL4xxxx

This RFC adds iWARP support to our QL4xxxx networking adapters.
The code changes span across qed and qedr drivers.

It is submitted as a single (long) RFC for purpose of reviewing,
but will eventually be split into two separate patch series,
one targeted for qed (net-next) and containing minimal qedr changes
and the other for qedr (rdma-next).

This series was tested and built against net-next.

qedr is used for both RoCE and iWARP. The distinction is made (for now)
at the pci function level. Code prefixed with rdma is shared, roce/iwarp
is specific.

The following was tested for iWARP under OFED: iser, nvmf, NFSoRDMA,
concurrent support of roce and iwarp on different pci functions.

MAINTAINERS file is not updated in this RFC as there is a pending patch
for qedr driver update https://patchwork.kernel.org/patch/9752761.

Your review and comments are highly appreciated.
