Title:
[SRU][Zesty] qcom_emac is unable to get ip address with at803x phy
driver.
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
qcom_emac is unable to get ip address with at803x phy driver. Use software
polling (PHY_POLL) to check for link state changes instead of relying on the
EMAC's hardware polling feature. Some PHY drivers are unable to get a
functioning link because the HW polling is not robust enough.
The emac interface is the onboard nic on the QDF2400 platform. A non
working emac would be a cert blocker for this platform.
[Test]
Boot the netboot DI installer on QDF2400, and chose the emac interface, the
install will fail because the emac interface is unable to get an IP lease.
Also, on an installed system the emac driver is unable to get ip address.
[Fix]
Patch is in Dave Miller's 'net' repo:
https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/id=246096690be0742d9bb5f3456d2cb95b68f7b46d
[Regression]
The patch is to emac driver which is only available on the QDF2400 platform
so there is no risk of regression to other ARM64 platforms or platforms based
on other architectures.
