FreeBSD 11.0 RC2 disables L2 caching for UDP over IPv6

Glen Barber from the FreeBSD project has announced the availability of the second RC (Release Candidate) development build of the upcoming FreeBSD 11.0 operating system.

The development of FreeBSD 11.0 continues at a fast pace, and it looks like some improvements have been made since last week's first Release Candidate build, such as the re-implementation of support for "nat global" in IPFW, FreeBSD's IPv6 and IPv4 stateful firewall.

The list of changes continues with improved detection of network bridges that aren't HotPlug capable, additional fixes to the LLVM/Clang compiler support, more build enhancements, as well as the disablement of L2 caching for the User Datagram Protocol (UDP) over IPv6 protocol.

Last but not least, FreeBSD 11.0 Release Candidate 2 is here to address a hang issue in vtnet, FreeBSD's VirtIO Ethernet driver, which might have occurred when the max_virtqueue_pairs setting was set to VTNET_MAX_QUEUE_PAIR. Of course, several other minor bugs reported by users since RC1 have been fixed as well.

If you plan on taking this second Release Candidate build of the upcoming FreeBSD 11.0 operating system for a test drive, we inform you that the ISO images are now available to download for 64-bit (amd64), 32-bit (i386), ARMv6, ARM64 (AArch64), PowerPC (PPC), PPC64 (PowerPC 64-bit), and SPARC64 hardware architectures.

However, please try to keep in mind that this is a pre-release version of the OS, which means that it isn't suitable to be used in production environments. The development cycle of FreeBSD 11.0 will continue with the third and most likely the last RC build. The final release of FreeBSD 11.0 should be out on September 9, 2016.
