When rebooting (exiting) from the BTX loader, make sure to restore the GDT from the correct segment, otherwise a triple fault would be caused. In some virtual environments (VMware, VirtualBox, etc) this could lead to a unhandled error or hang in the guest emulation software. Thanks to avg and jhb for a few hints in the right direction. Noticed by: Jeremy Chadwick (and many others)

This small change takes care of a race condition that can occur when both sides close at the same time. If that occurs, without this fix the connection enters FIN1 on both sides and they will forever send FIN|ACK at each other until the connection times out. This is because we stopped processing the FIN|ACK and thus did not advance the sequence and so never ACK'd each others FIN. This fix adjusts it so we *do* process the FIN properly and the race goes away ;-) Approved by: emaste (co-mentor)

Workaround for PCIe 4GB boundary issue Enforce a boundary of no more than 4GB - transfers crossing a 4GB boundary can lead to data corruption due to PCIe limitations. This change is a less-intrusive workaround that can be quickly merged back to older branches; a cleaner implementation will arrive in HEAD later but may require KPI changes. This change is based on a suggestion by jhb@.

Update if_de(4) to fix bugs - a combination of bitrot and busdma changes.

Do not allow directly recursive RFC3173 IPComp payload. While IPv6 does count iterations over next headers in ip6_input, we still disallow directly recursive IPComp payload in the KAME code. Security: CVE-2011-1547
