>Description:
	I have a system in Canada using PPPoE that the MTU of 1492
	doesn't seem to work for some of the M$ clients.  In RELENG_4_3
	I had been using the "set mtu 1450" as part of the configuration.
	After upgrading to RELENG_4_4 the "set mtu 1450" seems to be 
	ignored and always uses a MTU of 1492.  Downgrading only ppp to
	RELENG_4_3 fixes the problem.

	This machine is 800 miles away and in a different country.  I
	can do some simple debug from here, but I don't want to risk
	losing contact.

 Hi,
 
 Would you be able to send me an LCP log from both before and after 
 the upgrade ?  I can then determine what's changed in the way ppp 
 negotiates.
 
 You can fix things with ``set mtu max 1450''.

 Yes, using "set mtu max 1450" does work.  If this is required there
 needs to be a heads-up in UPDATING.  Otherwise other people are going to
 have some breakage, breakage becuase this does not seem to POLA.

I've mentioned using ``set mtu max'' in the man page, but it's a bit late to 
add something to UPDATING I'm afraid :(
