Hi all,
I have a server with 3 Intel Pro 1000 cards in it. I am using one for iSCSI.
I want to enable Jumbo frames for it only not the other 2 controllers.
Yes, you can.The e1000g driver support this.
All I needed to do is modify the /kernel/drv/e1000g.conf but how do I
modify it so only one of the cards is affected? Can there be config files
for each card? i.e. /kernel/drv/e1000g1.conf ?
No, you just need configure it in /kernel/drv/e1000g.conf.
For example, if you want to enable jumbo on e1000g1 only, you just need
modify the second zero of MaxFrameSize:
MaxFrameSize=0,3,0,0,0,0,0,0,0,0,0,0,0,0,0,0;
# 0 is for normal ethernet frames.
# 1 is for upto 4k size frames.
# 2 is for upto 8k size frames.
# 3 is for upto 16k size frames.
# These are maximum frame limits, not the actual ethernet frame
# size. Your actual ethernet frame size would be determined by
# protocol stack configuration (please refer to ndd command man
pages)
# For Jumbo Frame Support (9k ethernet packet)
# use 3 (upto 16k size frames)
For the meaning of MaxFrameSize, please refer to e1000g(7D).
