Wireless Leiden
>Environment:
10.0-RC3 FreeBSD 10.0-RC3 #0 r260039M: Sun Dec 29 22:04:42 CET 2013 ugen1.2: <product 0x772b vendor 0x0b95> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (200mA)
>Description:
USB-LAN adapters with the ASIX AX88772 chip do not work properly on 10.0-RC3, whereas thera are no problems with 9.0-RELEASE.
Ping and dhcp work, ssh and http do not.
Test setup consists of two ALIX.2 boards (uses CPU: Geode(TM) Integrated Processor by AMD PCS 498.06-MHz 586-class CPU and an AMD CS5536 (Geode) USB 2.0 controller)

Host9.0-RELEASE with httpd, sshd, dhcpd running, connected with utp-cable (tested) to host10.0-RC3 with usb-lan adapter connected:
ue0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8000b<RXCSUM,TXCSUM,VLAN_MTU,LINKSTATE> ether 00:00:00:00:00:01 inet6 fe80::200:ff:fe00:1 %ue0 prefixlen 64 scopeid 0x8  inet 172.16.6.77 netmask 0xfffffff8 broadcast 172.16.6.79  nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect (100baseTX <full-duplex>) status: active

Ping and dhcp from host10.0-RC3 to Host9.0-RELEASE is OK, but ssh and fetch (http) time out.

Same setup with both hosts running 9.0-RELEASE functions without problems
Same setup with hostRC10-RC3 and different usb-lan adapter works OK (I tested if_aue, if_udav and if_mos).




>How-To-Repeat:
setup a similar test with two hosts and this usb-lan adapter
