Hi, I have a Broadcom BCM5788 card that I'd like to use with jumboframes, but it seems that the card (or the driver) only allows a max of 1500 MTU.
ifconfig bge0 mtu 9000 ifconfig: ioctl (set mtu): Invalid argument 1500 and less works. I had this problem with my BCM5707M, and lo and behold if you look in if_bge.c it says it can't do it, but I looked and I can't find a similar comment for the BCM5788. Any thoughts? The system in question is 5.2.1-RELEASE-p3. The bge card is builtin to the motherboard (shuttle sb75g2 on 64 bit pci.) While I have everybody's attention, what's a reasonable goal for throughput between two of these cards? I broke through the 33mhz pci barrier and am now getting iperf results of: [ 6] 0.0-10.0 sec 535 MBytes 449 Mbits/sec ( Obviously, without jumbo frames.) I've increased the tcp send and recv space....Any other suggestions?
