John Baldwin 463edaf441 al: Replace boolean_t with either al_bool or bool. 
Use al_bool for interfaces and structures defined in the
OS-independent HAL in sys/contrib, and use plain bool for
FreeBSD-specific APIs and structures in sys/dev/al_eth.

Dimitry Andric 9ea31d78f0 al_eth: make function definitions consistent with declarations 
The declarations for al_eth_lm_retimer_ds25_signal_detect() and
al_eth_lm_retimer_ds25_cdr_lock() say that these functions return
'al_bool', but the definitions actually return 'boolean_t'.

Make the definitions match the declarations.

Gleb Smirnoff 57d361630d Convert to if_foreach_llmaddr() KPI. 
This driver seems to have a bug.  The bug was carefully saved during
conversion.  In the al_eth_mac_table_unicast_add() the argument 'addr',
which is the actual address is unused.  So, the function is called as
many times as we have addresses, but with the exactly same argument
list.  This doesn't make any sense, but was preserved.

Marcin Wojtas 0b5cab4e0f Use ip/ipv6 structures in al_eth only if they are supported 
The ip/ipv6 header files are included only if the appropriate definition
exists, but the driver was missing similar checks when using the
ip and ip6_hdr structures.

If the kernel was not built with the INET or INET6 option, the driver
was preventing kernel from being built.

To fix that, the missing ifdef checks were added to the driver.

Matt Macy d7c5a620e2 ifnet: Replace if_addr_lock rwlock with epoch + mutex 
Run on LLNW canaries and tested by pho@

gallatin:
Using a 14-core, 28-HTT single socket E5-2697 v3 with a 40GbE MLX5
based ConnectX 4-LX NIC, I see an almost 12% improvement in received
packet rate, and a larger improvement in bytes delivered all the way
to userspace.

When the host receiving 64 streams of netperf -H $DUT -t UDP_STREAM -- -m 1,
I see, using nstat -I mce0 1 before the patch:

Alexander Kabaev 151ba7933a Do pass removing some write-only variables from the kernel. 
This reduces noise when kernel is compiled by newer GCC versions,
such as one used by external toolchain ports.
