eth_recv out of MBUFs


hi,

i am working on a FCC driver for the MPC8260ADS.
(FCC driver is based on the Viper FEC driver)
cvs-version 02-Oct-2001

i am getting "warning: eth_recv out of MBUFs" messages
after while running the tcp_echo - "test suite".
sending only 100 packets instead of 1024 works fine.

What does this message mean, where should i
start in my driver code.

Any suggestions are appreciated

regards, christoph
