In dual emac mode, the CPSW subsystem provides two independent ethernets.
This is implemented (as recommended by TI's TRM) with a mixture of switch
settings (vlans) and specific features of CPSW subsystem.
The driver was splitted to accommodate the shared parts (RX and TX rings
for example) while it still provides two independent ethernets.
Each of the ethernet ports driver has it's own set of MDIO registers among
the other private settings.
Previously this driver always operate in promisc mode, now the Switch ALE
(address table entry) is properly initialized and enabled.
The driver is also tested (and known to work) with both ports operating in
single port mode (active_slave 0 or 1).
Tested on uBMC (dual emac mode, both ports in single mode, giga and fast
ethernet) and BBB (single port, fast ethernet).

socket option in this block of code. Also, use in6ifa_withaddr() instead
of ifa_withaddr().
We changed the ABI for ARM in 10, an removed support for the old ABI in 11,
as such binaries from these releases are unable to be run on a head kernel.

Figure out if the chip is counting PAUSE frames in the "normal" stats
and take them out if it is. This fixes a bug in the tx stats because
the default hardware behavior is different for Tx and Rx but the driver
was treating both the same way. The result was that OPACKETS, OBYTES,
and OMCASTS were under-reported (if tx_pause > 0) before this change.
Note that the mac_stats sysctl still gives you the raw value of these
statistics straight from the device registers.
during argument validity verification, unbound zero'ing of the process LDT
and adjacent memory can be initiated from usermode.

The following pheripherals are supported: UART, MMC, AHCI, EHCI, PCIe, I2C,
PMIC, GPIO, CPU temperature and clock.
Note: The PCIe driver is pure mash at this moment. It will be reworked

SYSCTL_COUNTER_U64_ARRAY() macro.
- Add proper asserts to the SYSCTL_COUNTER_U64_ARRAY() macro that checks
the size of the first element of the array.
- Add an example to the counter(9) manual page how to use the
SYSCTL_COUNTER_U64_ARRAY() macro.
- Add some missing symbolic links for counter(9) while at it.
When we guess the nature of the outbound packet (output vs. forwarding) we need
to take bridges into account. When bridging the input interface does not match
the output interface, but we're not forwarding. Similarly, it's possible for the
interface to actually be the bridge interface itself (and not a member interface).

This is several year's worth of fail point upgrades done at EMC Isilon. They
are interdependent enough that it makes sense to put a single diff up for them.
Primarily, we added:
- Changing all mainline execution paths to be lockless, which lets us use fail
points in more sleep-sensitive areas, and allows more parallel execution
- A number of additional commands, including 'pause' that lets us do some
interesting deterministic repros of race conditions
- The ability to dump the stacks of all threads sleeping on a fail point
- A number of other API changes to allow marking up the fail point's context in
the code, and firing callbacks before and after execution
- A man page update

Specifically this fixes /usr/lib/libc.so stripping the paths to the
libraries. The reason for this in r266227 was both likely because ld(1) did
not fully respect --sysroot until r291226 and because of the lib32
build. The lib32 build does not use --sysroot into the /usr/lib32 path,
rather it only uses -L and -B into the /usr/lib32 path and --sysroot
into the normal (64bit) /usr/lib. The _LDSCRIPTROOT was added with
the ldscript support in bsd.lib.mk so that it builds a 32-bit-sysrooted pathed
ldscript in the object directory and then installs a normal unprefixed
version in installworld. This commit also fixes the rebuild during
install which was broken in r266227. This commit would break DIRDEPS_BUILD
build of lib32 but it does not currently have a way to build it anyhow.
For example, before this change we had in /usr/lib/libc.so:
GROUP ( libc.so.7 libc_nonshared.a libssp_nonshared.a )
Now it is restored to pre-r266227:
GROUP ( /lib/libc.so.7 /usr/lib/libc_nonshared.a /usr/lib/libssp_nonshared.a )
The motivation for this is in testing of lld.
From emaste:
lld does not have built-in search paths (e.g. /lib, /usr/lib) and relies on
-L arguments passed by the caller. As the linker is nearly always invoked
from the clang driver this is fine other than the fact that /usr/lib/libc.so
is an ldscript that refers to libc.so.7 which is in /lib, not /usr/lib.
