Indeed that was the problem. This does not fix my browsing problems (though it 
does change the symptoms a bit), but share access is the far more important 

It appears to me that this issue is not documented anywhere in the SAMBA book. 
Perhaps a new section is in order? If someone wants to suggest the right 
place to put it, I'd be glad to write one. I can see several places where 
this could go:
Chapter 9, under "Browsing of Shares and Directories is Very Slow"
Chapter 37 (but where on the list do you try sending 1500-byte pings?)
Chapter 38, anywhere?

Chapter 37 seems the right choice to me. Maybe adjust paragraph 2 to suggest 
use of ping -s 1500 -M do?

Give me comments, and I'll make a patch.
