A part of this error message is related to the following status that is=20
returned by the Chipset:
if (stat_val & IDT_STAT_FBQ1A) {
printf("proatm%d: not enough large buffers.\n", proatm->u=
nit);
proatm_ld_rcv_buf(proatm, 0, 64);
}

ev=3D1.1.2.2&content-type=3Dtext/x-cvsweb-markup
According the the IDT77252's manual : "This field indicates that FBQ1 has=
=20
fewer empty free buffers than the value specified in the Threshold (THLD)=
=20
field of the Free Buffer Size 1 (FBQS1) register. This bit will be set on=
ly=20
if the Free Buffer Queue Interrupt Enable (FBQIE) bit of the Configuratio=
n=20
register is set to 1. This bit will return to zero one buffers are added =
to=20
the FBQ."
I do not understand why your HW is always requesting for more buffers !! =
Have=20
you done something special ?
Can you provide more information about your configuration ?
Could you try the same test without ipfw ?

Vincent
