[coLinux-users] How set MTU and txlen?

[<Use...@zo...>]

Hello

I ran into  the problem, that a "funny hub" on the way between
an SDSL and an ADSL Interface allows only an MTU of 1484!
That "funny hub" (maybe a hidden tunnel) fagments every paket which 
is greater than 1484 into a first paket of unusual 1000 bytes but
is not generating ICMP when DF sez set, so the correct MTU 
is undetectable by PMTUD.

How can set set the MTU permanently?

To my surprise i can set MTU only for IPsec, Why? What could be a usefull
application for a virtual device like ipsec0 not to use 16K?


But "PPoE" settings does not have such a field and no ethernets have.
Why?

How is the "intended" way to set other MTUs in IPcop fpr eth and PPPoE?

Why ist the TX length of PPPoE only 3? That value origins from old time
of ISDN an modens, or?Rainer---<=====>                         Vertraulich
