Mark Johnston 010ca539cb pf: Stop using net_epoch to synchronize access to eth rules
Commit 20c4899a8e modified pf_test_eth_rule() to not acquire the
rules read lock, so pf_commit_eth() was changed to wait until the
now-inactive rules are no longer in use before freeing them.  In
particular, it uses the net_epoch to schedule callbacks once the
inactive rules are no longer visible to packet processing threads.

However, since commit 812839e5aa, pf_test_eth_rule() acquires the
rules read lock, so this deferred action is unneeded.  This patch
reverts a portion of 20c4899a8e such that we avoid using deferred
callbacks to free inactive rules.

The main motivation is performance: epoch_drain_callbacks() is quite
slow, especially on busy systems, and its use in the DIOCXBEGIN handler
in particular causes long stalls in relayd when reloading configuration.

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
