Subject: [PATCH net 0/2] net: macb: Fix Ethernet malfunction on AMD Versal board after suspend
Date: Thu, 12 Mar 2026 16:13:57 +0800 [thread overview]
Message-ID: <20260312-macb-versal-v1-0-467647173fa4@gmail.com> (raw)
Hi,
On Versal boards, the tx/rx queue pointer registers are cleared after suspend,
which causes Ethernet malfunction. This patch series addresses this issue by
reinitializing the tx/rx queue pointer registers and the rx ring.
