The following device hint makes the driver use + I/O mapping for register access: + + hint.ste.N.prefer_iomap="1" + + The &man.sk.4; driver now disable TX + checksum offloading by default. This is because some + revision of Yukon controller generates corrupted frames. + The checksum offloading can be enabled manually by using + option in the &man.ifconfig.8; + utility.

This was limited to 64KB, and the number of + scatter/gather segments was limited to 33 on platforms with + 4K pages. + + The &man.twa.4; + driver has been updated. The version number is + 3.80.06.003. File Systems - + The ZFS on-disk format has been updated + to version 15. + + The ZFS metaslab code has been updated. + This provides a noticeable improvement on write speed, + especially on pools with less than 30% of free space.
