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.
