Intel EHL: Two of the on-board ethernet ports don't work

[Jesse Sung]

== Impact ==
Only one of the three on-board ethernet ports works. The other two can't get IP addresses.

== Fix ==
commit 884d2b845477cd0a18302444dc20fe2d9a01743e

    net: stmmac: Add GFP_DMA32 for rx buffers if no 64 capability

    Use page_pool_alloc_pages instead of page_pool_dev_alloc_pages, which
    can give the gfp parameter, in the case of not supporting 64-bit width,
    using 32-bit address memory can reduce a copy from swiotlb.

== Risk of Regression ==
Low. The commit changes gfp parameter only when there's no 64-bit capability, and it is already in mainline.

This bug is awaiting verification that the linux-intel-5.13/5.13.0-1009.9 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
