This is not dissimilar to the problem I identified in hdlcdrv which has a fixed
length buffer of 400 bytes.
I've identified a network driver interface that takes the mtu from ifconfig via
the pointer in the device structure (change_mtu) so I'm going to have a go at
that sometime soon using ~/linux/drivers/net/slip.c as an example!!
hdlcdrv affects baycom (all types), oe5dxl, g4xyw and soundcard modems but does
*not* affect the scc driver - the format of the fix may be relevant though.
