Does VMWare Workstation support jumbo frames?
An attempt to issue
/sbin/ifconfig vmnet7 mtu 9000
fails with
SIOCSIFMTU: Invalid argument
I run VMWare 6.5.2-156735 on RHEL-5.3, with 64 bit kernel (2.6.18-128.1.14.el5 #1 SMP Mon Jun 1 15:52:58 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux). My Ethernet (e1000e) driver supports jumbo frames.
Any ideas?

--Nope, last I heard no Vmware product that I know of supports TCP Jumbo frames in-guest or on Host-side adapters. (Maybe ESX does, I dunno.)
--That said, you really shouldn't need it. Vmware "ethernet" performance is mainly limited by CPU, not framesize - especially if you use Host-only net.

I meant UDP frames. We use UDP to broadcast scientific data to several computers on a local network and my VmWare 'team' was designed to test the software.

The new VMXNET3 adapter supports jumbo frames (when used in some guest operating systems). Not sure if that adapter has made it into your/current release of VMware workstation.
