Hi Doug,
This patchset adds RoCE V1 and RoCE V2 support to the mlx5 device
driver.
Question - assuming I read them correctly, these patches add the
RoCE v1 and RoCE v2 support on a per-port basis. That is, a port
can be either IB, RoCE v1 or RoCE v2, but not a combination.
Has any thought been put toward supporting these protocols on a
per-QP basis, i.e. the caller of rdma_connect() can specify the
desired protocol? Or to have some sort of discovery?
I know that there may be implementation restrictions on today's
devices, but it's my personal belief that future devices will
support multiple protocols (perhaps beyond the three above), and
laying the groundwork for this today will be important.
Tom.
This patchset was applied and tested over patchset "Add RoCE v2
support" which was sent to the mailing list by Matan Barak.
