Hi,
It looks like it is not possible to configure any MRU values with MPD, due to
LCP_MRU_MARGIN (=20).
For example, on the PPPoE links, the values between 1473 to 1491 are not
possible.
...
link.c:
case SET_MRU:
case SET_MTU:
val = atoi(*av);
name = ((intptr_t)arg == SET_MTU) ? "MTU" : "MRU";
if (!lnk->phys->type)
Log(LG_ERR, ("[%s] this link has no type set", lnk->name));
else if (val < LCP_MIN_MRU)
Log(LG_ERR, ("[%s] the min %s is %d", lnk->name, name, LCP_MIN_MRU));
else if (val + LCP_MRU_MARGIN > lnk->phys->type->mru)
Log(LG_ERR, ("[%s] the max %s on type \"%s\" links is %d",
lnk->name, name, lnk->phys->type->name,
lnk->phys->type->mru - LCP_MRU_MARGIN)); /* XXXXXXXXXX */
else if ((intptr_t)arg == SET_MTU)
lnk->conf.mtu = val;
else
lnk->conf.mru = val;
break;
...
I think that the LCP_MRU_MARGIN tests could be removed or LCP_MRU_MARGIN
could be set to 0.
Regards,
Vincent
