src-test2/lib/libstand, branch release/11.0.0

Fix a bug in the parsing code: always use the len and not 8.

Add support for %S to libstand as well so /boot/loader and friends can

use it.

libstand: make more use of the howmany() macro when available.

2016-04-26T01:19:36Z

We have a howmany() macro in the header that is convenient to re-use as it makes things easier to read.

Unbreak the build if you enable WITH_NAND

A new implementation of the loader block cache

2016-04-18T23:09:22Z

The block cache implementation in loader has proven to be almost useless, and in worst case even slowing down the disk reads due to insufficient cache size and extra memory copy. Also the current cache implementation does not cache reads from CDs, or work with zfs built on top of multiple disks. Instead of an LRU, this code uses a simple hash (O(1) read from cache), and instead of a single global cache, a separate cache per block device. The cache also implements limited read-ahead to increase performance. To simplify read ahead management, the read ahead will not wrap over bcache end, so in worst case, single block physical read will be performed to fill the last block in bcache. Booting from a virtual CD over IPMI: 0ms latency, before: 27 second, after: 7 seconds 60ms latency, before: over 12 minutes, after: under 5 minutes.

If the dhcp server delivers an interface-mtu option, parse it and store

2016-03-21T14:58:12Z

the value in a new global intf_mtu for use by the application. These changes were inspired by the patch provided by Robert Blayzor in PR 187094, and will allow loader(8) to propagate the value to the kernel along with the other nfs_diskless parms delivered via environment vars.

Actually garbage collect the unused code, as mentioned in r297147, which

this change should have been part of.
