718cf2ccb9 sys/dev: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

671bf2b8b2 cxgbe(4): Changes to the CPL-handler registration mechanism and code
related to "shared" CPLs.

a) Combine t4_set_tcb_field and t4_set_tcb_field_rpl into a single
function.  Allow callers to direct the response to any iq.  Tidy up
set_ulp_mode_iscsi while there to use names from t4_tcb.h instead of
magic constants.

b) Remove all CPL handler tables from struct adapter.  This reduces its
size by around 2KB.  All handlers are now registered at MOD_LOAD instead
of attach or some kind of initialization/activation.  The registration
functions do not need an adapter parameter any more.

c) Add per-iq handlers to deal with CPLs whose destination cannot be
determined solely from the opcode.  There are 2 such CPLs in use right
now: SET_TCB_RPL and L2T_WRITE_RPL.  The base driver continues to send
filter and L2T_WRITEs over the mgmtq and solicits the reply on fwq.
t4_tom (including the DDP code) now uses the port's ctrlq to send
L2T_WRITEs and SET_TCB_FIELDs and solicits the reply on an ofld_rxq.
fwq and ofld_rxq have different handlers that know what kind of tid to
expect in the reply.  Update t4_write_l2e and callers to to support any
wrq/iq combination.

90e7434a6d cxgbe(4): Add a struct sge_params to store per-adapter SGE parameters.
Move the code that reads all the parameters to t4_init_sge_params in the
shared code.  Use these per-adapter values instead of globals.

2da3897d01 Rename linuxapi[.ko] into linuxkpi[.ko], to reflect that it is a
kernel programming interface module, KPI, to avoid confusion with the
existing Linux userspace binary compatibility shims. Bump the
FreeBSD_version number.

b3d44a6800 cxgbe(4): tidy up some of the interaction between the Upper Layer
Drivers (ULDs) and the base if_cxgbe driver.

Track the per-adapter activation of ULDs in a new "active_ulds" field.
This was done pretty arbitrarily before this change -- via TOM_INIT_DONE
in adapter->flags for TOM, and the (1 << MAX_NPORTS) bit in
adapter->offload_map for iWARP.

iWARP and hw-accelerated iSCSI rely on the TOE (supported by the TOM
ULD).  The rules are:
a) If the iWARP and/or iSCSI ULDs are available when TOE is enabled then
   iWARP and/or iSCSI are enabled too.
b) When the iWARP and iSCSI modules are loaded they go looking for
   adapters with TOE enabled and enable themselves on that adapter.
c) You cannot deactivate or unload the TOM module from underneath iWARP
   or iSCSI.  Any such attempt will fail with EBUSY.

d39d7c8636 Add missing linuxapi module dependencies and always use the FreeBSD
"MODULE_VERSION" macro definition. Remove the redefinition of the
"MODULE_VERSION" macro from the Linux kernel compatibility API.
