It could be really helpful if you could find that standard papers :) I couldnt find anything from google. But I know normally ethernet interfaces just are not capable of sending packets larger than 1500 physically but only gigabit and wireless ethernets support this for some reason. Perhaps there should be a standart for this otherwise the producers wouldnt go into the trouble to support this huh? =) On Thu, 2 Jan 2003, Sten Daniel Sørsdal wrote: > > I believe I read somewhere that 802.11b standard supports larger MTUs than 1500. > I know basic ethernet MTU is 1500 but even my crappy old Nortel 8603 routing switch supports up to MTU 1960 > > Any corrections appreciated > > // Sten > > -----Original Message----- > From: David Magda [mailto:dmagda@magda.ca] > Sent: 2. januar 2003 21:59 > To: Evren Yurtesen > Cc: freebsd-stable@FreeBSD.ORG; wpaul@ctr.columbia.edu > Subject: Re: wi0 and mtu setting > > > Evren Yurtesen <eyurtese@turkuamk.fi> writes: > > > I wonder how come wi driver doesnt let me to set mtu higher than 1500 > > even though I know the card supports it? > > Because the maximum size of the data poriton in a frame for 10Mbit and 100Mbit Ethernet is 1500. > > > Will this be changed in a new version of the driver? > > Not unless they change the standard.
