[lwip-users] slip implementation bug

[marek]

Hello

Suppose that we have two interfaces: ETERNET and SLIP. We must set
PBUF_LINK_HLEN to 14 for ethernet and what about SLIP then ??

I found in slipif_input:

p = pbuf_alloc(PBUF_LINK_HLEN, PBUF_POOL_BUFSIZE, PBUF_POOL);

this code is working only with PBUFS smaller than (PBUF_POOL_BUFSIZE -
PBUF_LINK_HLEN)

my solution is to use PBUF_RAW instead of PBUF_LINK_HLEN in slipif_init.

Any others idea ?
