The real fix is : > to fix the driver to not require 2048 byte mbufs. : : I've looked at differences between pdq (DEC FDDI Controller) and idt(4). : It seems pdq does the right thing by specifying that it wants its buffers : to be 2048 bytes, using MCLGET() to ask for the cluster after the mbuf, : then using busdma to allocate the 2048 byte buffer. Don't let me stop you from fixing the driver or removing the test if the driver already has been fixed! Thanks for grunting out the details. It is much appreciated. Warner
