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 Author: David Wu <david...@rock-chips.com> Date: Mon Dec 13 19:15:15 2021 +0800 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. Signed-off-by: David Wu <david...@rock-chips.com> Signed-off-by: David S. Miller <da...@davemloft.net> == Risk of Regression == Low. The commit changes gfp parameter only when there's no 64-bit capability, and it is already in mainline. ** Affects: linux-intel-5.13 (Ubuntu) Importance: Undecided Assignee: Jesse Sung (wenchien) Status: Triaged ** Affects: linux-intel-5.13 (Ubuntu Focal) Importance: Undecided Assignee: Jesse Sung (wenchien) Status: In Progress ** Also affects: linux-intel-5.13 (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux-intel-5.13 (Ubuntu Focal) Assignee: (unassigned) => Jesse Sung (wenchien) ** Changed in: linux-intel-5.13 (Ubuntu Focal) Status: New => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1956413 Title: Intel EHL: Two of the on-board ethernet ports don't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-intel-5.13/+bug/1956413/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
