In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. A pointer from nesadapter back to
nesdev was added.

on implicit inclusion of this file (via netns/xfrm.h).
That won't work anymore when the flow cache is removed so include that

um/net_kern:
- remove pointless ndo_change_mtu
hsi/clients/ssi_protocol:
- use core MTU range checking
- remove now redundant ssip_pn_set_mtu
ipoib:
- set a default max MTU value
- Note: ipoib's actual max MTU can vary, depending on if the device is in
connected mode or not, so we'll just set the max_mtu value to the max
possible, and let the ndo_change_mtu function continue to validate any new
MTU change requests with checks for CM or not. Note that ipoib has no
min_mtu set, and thus, the network core's mtu > 0 check is the only lower
bounds here.
mptlan:
- use net core MTU range checking
- remove now redundant mpt_lan_change_mtu
fddi:
- min_mtu = 21, max_mtu = 4470
- remove now redundant fddi_change_mtu (including export)
fjes:
- min_mtu = 8192, max_mtu = 65536
- The max_mtu value is actually one over IP_MAX_MTU here, but the idea is to
get past the core net MTU range checks so fjes_change_mtu can validate a
new MTU against what it supports (see fjes_support_mtu in fjes_hw.c)

- min_mtu = 0 (calls ether_setup, max_mtu is 1500)

Support for Packed and Unaligned (PAU) FPDUs is needed for
interoperability between NES and non-NES nodes. When the NES hardware
detects a PAU frame, it will pass it to the driver to process the
frame. NES driver creates a new frame for each FPDU and forwards it
to the hardware to be sent to its associated qp.

In case of SFP+ PHY, link status check at interrupt processing can
give false results. For proper link status change detection a delayed
recheck is needed to give nes registers time to settle. Add a
periodic link status recheck scheduled at interrupt to detect
potential delayed registers state changes.

Fix some bugs with the max_aggr module parameter added with LRO support:
- The module parameter value ignored and not actually used to set
lro_mgr.max_aggr.
- MODULE_PARM_DESC had a typo "_mro_" instead of "_lro_" so it didn't
end up describing the actual module parameter.
- The nes_lro_max_aggr variable was declared as unsigned, but the
module_param line said "int" instead of "uint" for the type.
- The default value for the parameter was stuck in the permissions
field of module_param, which led to nonsensical permissions for the
file under /sys/module/iw_nes/param.
- The parameter was used in only one file but defined in another, which
led to the variable being global for no good reason. Move everything
related to the parameter to the file nes_hw.c where it is actually
used.
