Subject: [PATCH 0/1] Fix Aspeed ast2600 MAC TX hang
Date: Wed, 14 Oct 2020 14:06:31 +0800 [thread overview]
Message-ID: <20201014060632.16085-1-dylan_hung@aspeedtech.com> (raw)
This patch fixes the TX hang issue on Aspeed AST2600.
Two HW arbitration features are added onto ast2600, but these features will
cause MAC TX to hang when handling scatter-gather DMA. These two
problematic features can be disabled by setting MAC register 0x58 bit28
and bit27.
