I recently did a http install of SL6.1 as a virtualisation host. One of the network interfaces is a Atheros Communications AR8131 Gigabit Ethernet (rev c0) using the ATL1C driver.
One of the host machines (under KVM) has a https web interface (Vyatta). Attempting to reach this interface via the above bridged interface resulted in a corrupted page. Wireshark indicated that there was multiple “Broken TCP” packets. A web search revealed that the atl1c driver had/has issues with kernel 2.6.32. Did a pci/device ID check at Elrepo which reported that the atl1e driver was usable. Quick install with … yum install http://elrepo.org/linux/elrepo/el6/x86_64/RPMS/kmod-atl1e-1.0.1.14-1.el6.elrepo.x86_64.rpm Blacklisted the atl1c driver… vi /etc/modprobe.d/blacklist-net.conf blacklist atl1c Followed by a reboot. Https page now loads correctly and no broken TCP messages in Wireshark. Also got rid of some ssh issues (garbled decryption). Just a FYI post and to say thanks to Elrepo.
