Public bug reported:
== 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.
