• Many changes not listed here.
• Fix "heap full" errors in the amd64 boot loader when loading microcode.
• Add support in com(4) for Exar XR17V354 4-port devices.

• Make mandoc(1) define a previously undefined integer as being zero.
• Make ksh(1) support 64bit integer operations on 32bit arches too.
• Added octcrypto(4), a driver for the octeon cryptographic unit, providing hardware-accelerated implementations for several encryption and authentication algorithms for ipsec(4). Disabled for now.
• Make smtpd(8) spfwalk check for legitimate IPv4 and IPv6 addresses before printing.
• Make headers, manpages and kernel prefer and recommend AF_UNIX name rather than AF_LOCAL.
• In kqueue, test for preexisting conditions when re-enabling events.
• Make pcidump(8) print BARs for bridges as well.
• On amd64, add support for EFI Random Number Generator and use it to XOR random data into the kernel.
• Add a hook to the standalone boot code to use a firmware-supplied random function in addition of the machine dependent random function to insert entropy into the booted kernel.
• IPv6 fix for gif(4).
• Attach the mbuf tag on output gif(4) packets to suppress loops over the interface and avoid leak of the tag on every packet.
• For certain arm devices, if the PHY address isn't specified, only attach a single PHY. Makes Theobrama Systems RK3399-Q7 SoM network interfaces work.
