freebsd with flexible iflib nic queues

reset command. I observed some anomalous behavior while testing a 3c905C with a Dell PowerEdge 4300/500 dual PIII 500Mhz system. The NIC would seem to work correctly most of the time but would sometimes fail to receive certain packets, in particular NFS create requests. I could mount an NFS filesystem from the PowerEdge and do an ls on it, but trying to do a "touch foo" would hang. Monitoring traffic from another host revealed that the client was properly sending an NFS create request but the server was not receiving it. It *did* receive it when I ran the same test with an Intel fxp card. I don't understand the exact mechanics of this strange behavior, but resetting the receiver and transmitter seems to get rid of it. I used to perform an RX and TX reset in xl_init(), but stopped doing it there because on 3c905B and later cards this causes the autoneg session to restart, which would lead to the NIC waiting a long time before exchanging traffic after being brought up the first time. Apparently the receiver and transmitter resets should be performed at least once when initializing the card. Hopefully this will cure problems that people have been having with the 3c905C -- this was the only strange behavior that I have observed with the 3c905C so far which does not appear with the 3c905B or 3c905. |

UPDATING |
This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.13 1998/09/13 09:38:34 markm Exp $ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel and the contents of /etc. Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
