Re: Latest nvnet network driver prevents setting MTU < 1500
replying to my own post.....
I changed to the forcedeth driver (alias eth0 forcedeth) instead of the nvnet driver, and everything works fine, I can set the MTU value to whatever is required. Anyone else seeing odd network problems with sites above a certain size, or emails bigger than a certain size failing should probably try this....
(FI, by editing /etc/sysconfig/network-scripts/ifcfg-eth0 and adding MTU=xxxx - in my case xxxx=1458)
Seems an odd restriction to make in a network driver, I thought any packet size was valid, right down to 0 (not that just sending the header and no data would do you any good, but hey).
