If CONFIG_IPV6 is not enabled in the kernel, tcp.h is not included
implicitly from other header files, causing compilation errors. To
solve that, explicitly include it in tx-gen2.c.
iwlwifi: pcie: don't access periphery registers when not available
The periphery can't be accessed before we set the
INIT_DONE bit which initializes the device.
A previous patch added a reconfiguration of the MSI-X
tables upon resume, but at that point in the flow,
INIT_DONE wasn't set. Since the reconfiguration of the
MSI-X tables require periphery access, it failed.
The difference between WoWLAN and without WoWLAN is that
in WoWLAN, iwl_trans_pcie_d3_suspend clears the INIT_DONE
without clearing the STATUS_DEVICE_ENABLED bit in the
software status. Because of that, the resume code thinks
that the device is enabled, but the INIT_DONE bit has been
cleared.
To fix this, don't reconfigure the MSI-X tables in case
WoWLAN is enabled. It will be done in
iwl_trans_pcie_d3_resume anyway.

/announce/ it with a "monitor" flag in the "cap" iovar. There isn't any
reliable detection method for older firmwares (BRCMF_C_MONITOR was tried
but "it only indicates the core part of the stack supports").
Similarly support for tagging monitor frames and building radiotap

In addition, the init flow changes so the firmware is loaded
by the IML, and so we must allocate the IML on the DRAM and
give the ROM the IML's address before kicking the firmware's
self init.

iwlwifi: pcie: allocate and free rx cr's and tr's tails
The hw now refers to two new blocks:
* rx tr tail - The Tail index on the free buffers queue TR,
which is update by the device after reading the free buffer
from the tr.
* rx cr tail - Updated by the driver when completing
processing a new completion descriptor in the cr.
Add these two new struct to the rxq, allocate and free them
when needed.
In addition, the register for rx write pointer had been changed
to HBUS_TARG_WRPTR. The way to differentiate tx from rx is the
queue number. TX range is 0-511, and RX's is 512-527.

iwlwifi: allow different csr flags for different device families
Different device families may have different flag values
for passing a message to the fw (i.e. SW_RESET).
In order to keep the code readable, and avoid conditioning
upon the family, store a value for each flag, which indicates
the bit that needs to be enabled.
Additionally, support 22560 device csr flags and addresses.
