Description

I upgraded my 2.1-DEVELOPMENT box from 2.1-DEVELOPMENT from several
months ago and my re(4) a RTL8101E card only works for a few seconds
after boot. After which I get watchdog timeouts and am unable to ping
a remote host. I was unable to get any information from tcpdump.
Here is the relevant verbose dmesg output and sysctl output. I have
tried disabling rx/tx csum and vlan{mtu,hwtagging} all to no avail. Let
me know what further info is needed.

re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=1b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
inet6 fe80::2a0:d1ff:fe60:25a3%re0 prefixlen 64 scopeid 0x1
inet x.x.x.x netmask 0xffffffc0 broadcast x.x.x.x
ether 00:a0:d1:60:25:a3
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active

Does sysctl hw.re0.imtype=0 help?

I failed to mention I tried that as well. It did not work.

That works. I'm not sure if that needs be removed for all cards to I
made this patch. Also I'm not sure if the 8102 cards need this or
not. Thanks for your help on this.

Thank you for testing. I think we should not set max read request
size on all 10/100 only NICs. Please test following patch:
