[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. |

[Regression Potential]
* The patchset touches a lot of the sfc driver, so the potential
for regression definitely exists. Thus, a lot of consideration
and testing happened:
* It has been tested on other adapter which uses the old code,
and no regressions were found so far (see 7000 series above).
* The patchset essentially moves the driver in Bionic up in the
upstream 'git log':
- since commit d4a7a8893d4c ("sfc: pass valid pointers from efx_enqueue_unwind")
- until commit 7f61e6c6279b ("sfc: support FEC configuration through ethtool")
- except for 2 commits (not needed / unrelated)
- commit 42356d9a137b ("sfc: support RSS spreading of ethtool ntuple filters")
- commit 9baeb5eb1f83 ("sfc: falcon: remove duplicated bit-wise or of LOOPBACK_SGMII")
- plus 2 more recent commits (fixes)
- commit 458bd99e4974 ("sfc: remove ctpio_dmabuf_start from stats")
- commit 0c235113b3c4 ("sfc: stop the TX queue before pushing new buffers")
* The patchset is exclusively cherry-picks, no single backport. |

(Medford2 / SFC9250) in the Bionic 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. Thus, a lot of consideration
and testing happened:
* It has been tested on other adapter which uses the old code,
and no regressions were found so far (see 7000 series above).
* The patchset is exclusively cherry-picks, no single backport.
* The patchset essentially moves the Bionic driver up in the
upstream 'git log --oneline -- drivers/net/ethernet/sfc/':
- since commit d4a7a8893d4c ("sfc: pass valid pointers from efx_enqueue_unwind")
- until commit 7f61e6c6279b ("sfc: support FEC configuration through ethtool")
- except for 2 commits (not needed / unrelated)
- commit 42356d9a137b ("sfc: support RSS spreading of ethtool ntuple filters")
- commit 9baeb5eb1f83 ("sfc: falcon: remove duplicated bit-wise or of LOOPBACK_SGMII")
- plus 2 more recent commits (fixes)
- commit 458bd99e4974 ("sfc: remove ctpio_dmabuf_start from stats")
- commit 0c235113b3c4 ("sfc: stop the TX queue before pushing new buffers") |
