NetBSD looks like it has support for it. Now I may be wrong here, but it appears that the BCM57765 is similar to other devices based on the NetBSD if_bge.c source version 1.194. I've tried applying the NetBSD changes to the FreeBSD bge source but I don't know enough about the hardware and the code is different enough that I haven't made it very far. I can get a patched 8.2 kernel to detect the device, complain that the ASIC is unknown, read the MAC address correctly and determine there is link but as soon as you attempt to ifconfig up the interface the machine locks up. I'm happy to try and port this over but need a nudge in the right direction from someone who knows the code. Here is experimental patch for BCM57765 family controllers. I don't have these controllers so the patch was not tested at all except compile. Recent Broadcom controllers like BCM57765 support EEE(Energy Efficient Ethernet) feature but it is not yet supported by the patch. Also it would good to see the output of pciconf -lcbv and dmesg after applying the patch.

I've been away from the machines with this chipset for the past week so have not finished the testing, but can report that the initial tests I did involving normal use, jumbo frames, v4 and v6 etc. all worked fine and throughput was good. Once I have done a thorough test of the NIC I will post a report here.

I tested it with both 57765X and 57785X. All seems to work as expected. Jumbo frame performance also looks very good. Once I have done a thorough test of the NIC I will post a report here.

gdb scripts for mbuf leaks
Hi, I am trying to track down an mbuf leak caused by an in-kernel custom application. Does anyone here have any gdb scripts that would traverse the zone (zone mbuf in this case) and print out all objects that are currently allocated? -vijay PS: I see the count of mbufs (current/cache/total) going up constantly. ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to freebsd-net-unsubscr...@freebsd.org
