Subject: [PATCH net-next 1/3] macb: add RM9200's interrupt flag TBRE
Date: Sun, 11 Oct 2020 11:09:42 +0200 [thread overview]
Message-ID: <20201011090944.10607-2-w@1wt.eu> (raw)
In-Reply-To: <20201011090944.10607-1-w@1wt.eu>
Transmit Buffer Register Empty replaces TXERR on RM9200 and signals the
sender may try to send again becase the last queued frame is no longer
in queue (being transmitted or already transmitted).
