Subject: [PATCH 09/15] hw/net/e1000e: Fix impl.min_access_size
Date: Sat, 19 Jun 2021 10:26:20 -0700 [thread overview]
Message-ID: <20210619172626.875885-10-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210619172626.875885-1-richard.henderson@linaro.org>
There are certainly architectural 2 byte writes, as evidenced
by the e1000e_set_16bit function. I also saw a 1 byte write,
though that may have been the fuzzer.
