---help---
Provides the size of the SLIP packet buffers.
The Linux slip module hard-codes its MTU size to 296 (40 bytes for
the IP+TPC headers plus 256 bytes of data). So you might as well
set CONFIG_NET_SLIP_MTU to 296 as well.
There may be an issue with this setting, however. I see that Linux
uses a MTU of 296 and window of 256, but actually only sends 168
bytes of data: 40 + 128. I believe that is to allow for the 2x
worst cast packet expansion. Ideally we would like to advertise the
256 MSS, but restrict transfers to 128 bytes (possibly by modifying
the tcp_mss() macro).
