Question "receive buffer overflow" with wavelan driver 

Forum: PCMCIA Wireless Network Adapter Issues
Date: 2000, Apr 02
From: John Ruttenberg rutt

I am running linux 2.2.14 and pcmcia 3.1.13 on a new dell
inspiron 5k.  Sometimes during largish downloads, I get the
following messages:

    ewrfp 2368 lp->rfp 3954 
    Apr  2 11:48:25 alice kernel: eth0: wv_interrupt():     receive buffer overflow 
    Apr  2 11:48:25 alice kernel: eth0: wv_packet_rcv(): no    new frame: i593_rfp 3181 stop 4627 newrfp 6559 lp->rfp 182 

Here is a more complete extract from the syslog:
