Vast majority of rtalloc(9) users require only basic info from
route table (e.g. "does the rtentry interface match with the interface
I have?". "what is the MTU?", "Give me the IPv4 source address to use",
etc..).
Instead of hand-rolling lookups, checking if rtentry is up, valid,
dealing with IPv6 mtu, finding "address" ifp (almost never done right),
provide easy-to-use API hiding all the complexity and returning the
needed info into small on-stack structure.
This change also helps hiding route subsystem internals (locking, direct
rtentry accesses).
Additionaly, using this API improves lookup performance since rtentry is not
locked.
(This is safe, since all the rtentry changes happens under both radix WLOCK
and rtentry WLOCK).

The script that generates these makefiles was changed to modify LIBADD
rather than LDADD/DPADD, but the makefile itself was also changed in a
slightly different way.
r281257 added support for lazyload mode by allowing dtrace(1) to register
a DOF section on behalf of a traced process. This was implemented by
having libdtrace copy the DOF section into a heap-allocated buffer and
passing its address to the ioctl handler. However, DTrace uses the DOF
section address as a lookup key in certain cases, so the ioctl handler
should be given the target process' DOF section address instead. This
change modifies the ADDDOF handler to copy the DOF section in from the
target process, rather than from dtrace(1).
These helper functions can be used to read in or write a buffer from or to
an arbitrary process' address space. Without them, this can only be done
using proc_rwmem(), which requires the caller to fill out a uio. This is
onerous and results in code duplication; the new functions provide a simpler
interface which is sufficient for most existing callers of proc_rwmem().
This change also adds a manual page for proc_rwmem() and the new functions.

The pcb is saved at the top of the kernel stack on x86 platforms.
The initial kenrel stack pointer is set in the TSS so that the trapframe
from user -> kernel transitions begins directly below the pcb and grows
down.
The XSAVE changes moved the FPU save area out of the pcb and into a
variable-sized area after the pcb. This required updating the expressions
to calculate the initial stack pointer from 'stacktop - sizeof(pcb)' to
'stacktop - sizeof(pcb) + FPU save area size'.
The i386_set_ioperm() system call allows user applications to access
individual I/O ports via the I/O port permission bitmap in the TSS.
On FreeBSD this requires allocating a custom per-process TSS instead of
using the shared per-CPU TSS.
The expression to initialize the initial kernel stack pointer in the
per-process TSS created for i386_set_ioperm() was not properly updated
after the XSAVE changes. Processes that used i386_set_ioperm() would
trash the trapframe during subsequent context switches resulting in
panics from memory corruption.
This changes fixes the kernel stack pointer calculation for the per-process
TSS.

This will save time generating dependency files that we didn't expect
due to cases where SRCS!=OBJS or for building custom targetted objects
in Makefiles that do not end up in the DEPENDOBJS list.
This uses a bmake trick to modify CFLAGS based on ${.TARGET}. A

Rather than try to guess at all of the OBJS variables just use SRCS
using the same patterns that mkdep does. This also fixes a mistake
where dependencies were being generated with FAST_DEPEND when they were
not for mkdep. This happens when OBJS!=SRCS as is the case in
gnu/lib/csu where SRCS has 1 file and OBJS has several other files that
does not even contain the 1 SRCS file. Generally in these cases the
OBJS have custom dependencies defined in their Makefile. If we generate
dependencies for those and then load a .depend file, then .IMPSRC may
contain duplicate sources and lead to errors such as:
cc: error: cannot specify -o when generating multiple output files

This API include the following features:
1) vlan filter - for VST/VGT+ support.
2) spoofcheck.
3) robust functionality to allow/drop general untagged/tagged traffic.
4) support for both ingress and egress ACL types.
- Added loopback filter to the vacl table.
- Added multicast list set in the vPort context
- Added promiscuous mode set in the vPort context
- Set the vlan list in vPort context
1) Check caps if VLAN list is not longer than FW supports
2) Set MODIFY_NIC_VPORT_CONTEXT command
- Changed MLX5_EEPROM_MAX_BYTES from 48 to 32 so that a single EEPROM
reading cannot cross the 128-byte boundary. Previously reading the
MCIA register was done in batches of 48 bytes. The third reading
would then by-pass the 127th byte, which means that part of the low
page and part of the high page would be read at the same time, which
created a bug:
1st: 0-47 bytes
2nd: 48-95 bytes
