controller. L1 has several threshold/timer registers and they
seem to require careful tuned parameters to get best
performance. Datasheet for L1 is not available to open source
driver writers so age(4) focus on stability and correctness of
basic Tx/Rx operation. ATM the performance of age(4) is far from
optimal which in turn means there are mis-programmed registers or
incorrectly configured registers.
Currently age(4) supports all known hardware assistance including
- MSI support.
- TCP Segmentation Offload.
- Hardware VLAN tag insertion/stripping.
- TCP/UDP checksum offload.
- Interrupt moderation.
- Hardware statistics counter support.
- Jumbo frame support.
- WOL support.
L1 gigabit ethernet controller is mainly found on ASUS
motherboards. Note, it seems that there are other variants of
hardware as known as L2(Fast ethernet) and newer gigabit ethernet
(AR81xx) from Atheros. These are not supported by age(4) and
requires a seperate driver. Big thanks to all people who reported
feedback or tested patches.

The size of the extra data is allocated opaquely and this file

This is BSD licensed code written specifically for FreeBSD.
It initialises using SYSINIT so that the SDT provider, probe and

superpage-aligned virtual address for the mapping. Revision 1.65
implemented an overly simplistic and generally ineffectual method for
finding a superpage-aligned virtual address. Specifically, it rounds
the virtual address corresponding to the end of the data segment up to
the next superpage-aligned virtual address. If this virtual address
is unallocated, then the device will be mapped using superpages.
Unfortunately, in modern times, where applications like the X server
dynamically load much of their code, this virtual address is already
allocated. In such cases, mmap(2) simply uses the first available
virtual address, which is not necessarily superpage aligned.
This revision changes mmap(2) to use a more robust method,
specifically, the VMFS_ALIGNED_SPACE option that is now implemented by
vm_map_find().

Currently if any files are ignored, bsdtar will exit with a non-zero
exit status; this is likely to change in the future, but requires some
API changes in libarchive.

- verified that the ifp->if_snd.ifq_mtx was initalized for
all attached interfaces. This was pointless because it was
initalized for all interfaces in if_attach() so I've removed it.
- Checked that ifp->if_snd.ifq_maxlen is initalized and set it to
ifqmaxlen if unset. This makes more sense in if_attach() so
I moved it there.
- The first call of if_slowtimo(). Delete if_check() and call
if_slowtimo() directly from the SYSINIT().
All shim hooks are defined here. This is the interface between BSD
code in FreeBSD and CDDL code from OpenSolaris.
The hooks defined here are pre-processed out from the source files
when the KDTRACE_HOOKS kernel option isn't defined.
Note that this implementation differs from the one in OpenSolaris, so
it is BSD licensed and can be included anywhere.
The kernel definitions defined here are dependent on the kernel option
KDTRACE_HOOKS so that macros added to the sources are pre-processed
out completely when the DTrace kernel hooks aren't compiled in.
the mentioned PR:
- bounds check time->month as it is used as an array index
- fix usage of time->month as array index (month is 1-12)
- fix calculation based on time->day (day is 1-31)
- fix the speedup code as it doesn't calculate correct timestamps before
the year 2000 and reduce the number of calculation in the year-by-year code
- speedup month calculations by replacing the array content with cumulative
values
- add microseconds calculation
- fix an endian problem
