Revert r338177, r338176, r338175, r338174, r338172 After long consultations with re@, core members and mmacy, revert these changes. Followup changes will be made to mark them as deprecated and prent a message about where to find the up-to-date driver. Followup commits will be made to make this clear in the installer. Followup commits to reduce POLA in ways we're still exploring. It's anticipated that after the freeze, this will be removed in 13-current (with the residual of the drm2 code copied to sys/arm/dev/drm2 for the TEGRA port's use w/o the intel or radeon drivers). Due to the impending freeze, there was no formal core vote for this. I've been talking to different core members all day, as well as Matt Macey and Glen Barber. Nobody is completely happy, all are grudgingly going along with this. Work is in progress to mitigate the negative effects as much as possible. Requested by: re@ (gjb, rgrimes)

# DEVICE_POLLING adds support for mixed interrupt-polling handling
|

# of network device drivers, which has significant benefits in terms
|
||
# of robustness to overloads and responsivity, as well as permitting
|

# accurate scheduling of the CPU time between kernel network processing

# and other activities. The drawback is a moderate (up to 1/HZ seconds)
|

# potential increase in response times.
|

# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
|

# The virtio entry provides a generic bus for use by the device drivers.

# Multiple such interfaces are defined by the VirtIO specification. FreeBSD
|

# only has support for PCI. Therefore, virtio_pci must be statically
|
||
# compiled in or loaded as a module for the device drivers to function.
