Public bug reported:
[Impact]
* Support for Solarflare X2542 network adapter
(Medford2 / SFC9250) in the sfc driver.
* This network adapter is present on recent hardware,
at least HP 2019 and Dell PowerEdge R740xd systems.
* On recent-hardware deployments that would rather use
the Bionic LTS / GA supported kernel and cannot move
to HWE kernels this adapter is non functional at all.
[Test Case]
* The X2542 adapter has been exercised with iperf3 and nc
across 2 hosts on 25G link speed w/ MTUs 1400/1500/9000
on both directions, for 1 week.
Its performance is on par with the Cosmic 4.18 kernel
(which contains all these patches) and the out-of-tree
driver from the vendor.
* The 7000 series adapter (for regression testing an old model,
supported previously) has been exercised with iperf and netperf
(TCP_STREAM, UDP_STREAM, TCP_RR, UDP_RR, and TCP_CRR) in one
host (client/server in different adapter ports isolated with
network namespaces, so traffic goes through the network switch),
on 10G link speed on MTUs 1500/9000, for 1 weekend.
No regressions observed between the original and test kernels.
[Regression Potential]
* The patchset touches a lot of the sfc driver, so the potential
for regression definitely exists. It has been tested on other
adapter which uses the old code, and no regressions were found.
