The driver needs to provide a LinuxKPI device structure to register
itself with the IB subsystem. It was erroneously using a copy of its
FreeBSD device structure for this purpose.
Use linux_pci_attach_device() instead, following the example of the
Chelsio iwarp driver. Also ensure that we don't leak the faked device
during detach.

Remove unused #includes of a LinuxKPI header noticed while trying to
solve LinuxKPI struct net_device and related functions.
This takes qlnxr out of the picture of D29366.

X-D-R: D29366 (extracted as further cleanup)
upper_32_bits() and lower_32_bits() are defined twice in this file.
With the extra conditinal removed on LinuxKPI in 3b1ecc9fa1
they are also included from there already. Use the LinuxKPI version
and remove the two local ones.

r360870 added linux/slab.h into liunx/bitmap.h and this include linux/types.h
The qlnx driver is redefining some of those types so remove them and add an
explicit linux/types.h include.

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.
Mark all obvious cases as MPSAFE. All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

This fixes 32-bit compat (no ioctl command defintions are required
as struct ifreq is the same size). This is believed to be sufficent to
fully support ifconfig on 32-bit systems.

QL_ALIGN is a set of copies of roundup2, but it was missing an outer set
of parentheses, which began to matter with r324538. Now, fully copy the
parenthesization of roundup2.

2. Use sysctls for TRACE_LRO_CNT and TRACE_TSO_PKT_LEN
3. remove unused mtx tx_lock
4. bind taskqueue kernel thread to the appropriate cpu core
5. when tx_ring is full, stop further transmits till at least 1/16th of the Tx Ring is empty. In our case 1K entries. Also if there are rx_pkts to process, put the taskqueue thread to sleep for 100ms, before enabling interrupts.
6. Use rx_pkt_threshold of 128.

- Move all bitmap related functions from bitops.h to bitmap.h, similar
to what Linux does.
- Apply some minor code cleanup and simplifications to optimize the
generated code when using static inline functions.
- Implement the following list of bitmap functions which are needed by
drm-next and ibcore:
- bitmap_find_next_zero_area_off()
- bitmap_find_next_zero_area()
- bitmap_or()
- bitmap_and()
- bitmap_xor()
- Add missing include directives to the qlnxe driver
