to be 64-bit on 32-bit architectures. It is not uncommon for device trees
to use the upper 32-bits to store what effectively is an index into the
parent ranges property. In this case, when running with a 32-bit bus_addr_t
and bus_size_t, we would previously truncate the address, this may then
incorrectly match the wrong range, and return the wrong address.

Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources. For
now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of
u_long.
Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

- Avoid main lock contention by trylock for if_start, if that fails,
schedule TX taskqueue for if_start
- Don't do direct sending if the packet to be sent is large, e.g.
TSO packet.
This change gives me stable 9.1Gbps TCP sending performance w/ TSO
over a 10Gbe directly connected network (the performance fluctuated
between 4Gbps and 9Gbps before this commit). It also improves non-

The page information array could contain up to 32 elements (i.e. 512B).
And on network side w/ TSO, 11+ (176B+) elements, i.e. ~44K TSO packet,

support frameworks(i.e. reset/regulators/phy/tsensors/fuses...).
The clock framework significantly simplifies handling of complex clock
structures found in modern SoCs. It provides the unified consumers
interface, holds and manages actual clock topology, frequency and gating.
It's tested on three different ARM boards (Nvidia Tegra TK1, Inforce 6410 and
Odroid XU2) and on one MIPS board (Creator Ci20) by kan@.
The framework is still far from perfect and probably doesn't have stable
interface yet, but we want to start testing it on more real boards and
different architectures.

The iWARP Connection Manager (CM) on FreeBSD creates a TCP socket to
represent an iWARP endpoint when the connection is over TCP. For
servers the current approach is to invoke create_listen callback for
each iWARP RNIC registered with the CM. This doesn't work too well for
INADDR_ANY because a listen on any TCP socket already notifies all
hardware TOEs/RNICs of the new listener. This patch fixes the server
side of things for FreeBSD. We've tried to keep all these modifications
in the iWARP/TCP specific parts of the OFED infrastructure as much as
possible.
