Subject: [PATCH 2/2] Add parport support for Asix device 99100
References: <20220806113124.608017725@osadl.org>

For some reason, Asix decided to produce a parallel port that is fully
compatible with Netmos device 9900, but named it 99100. It obviously has
another vendor ID, but the device ID is the same. This patch adds the 
required settings and was successfully tested with the Asix device.
