Whenever a port gets enabled/disabled, recalcultate the required switch
clock rate to make sure it always gets set to the expected rate
targeting our switch use case. This is only done for the BCM7445 switch
as there is no clocking profile available for BCM7278.

We disable clocks shortly after probing the device to save as much power as
possible in case the interface is never used. When bcm_sysport_open() is
invoked, clocks are enabled, and disabled in bcm_sysport_stop().
A similar scheme is applied to the suspend/resume functions.

While CHELSIO_INLINE_CRYPTO is a guard symbol, and just enabling it does
not cause any additional code to be compiled in, all configuration
options protected by it depend on CONFIG_CHELSIO_T4. Hence it doesn't
make much sense to bother the user with the guard symbol question when
CONFIG_CHELSIO_T4 is disabled.
Fix this by moving the dependency from the individual config options to
the guard symbol.

If tg3_reset_task() fails, the device state is left in an inconsistent
state with IFF_RUNNING still set but NAPI state not enabled. A
subsequent operation, such as ifdown or AER error can cause it to
soft lock up when it tries to disable NAPI state.
Fix it by bringing down the device to !IFF_RUNNING state when
tg3_reset_task() fails. tg3_reset_task() running from workqueue
will now call tg3_close() when the reset fails. We need to
modify tg3_reset_task_cancel() slightly to avoid tg3_close()
calling cancel_work_sync() to cancel tg3_reset_task(). Otherwise
cancel_work_sync() will wait forever for tg3_reset_task() to
finish.

Change the default value of hard_header_len in hdlc.c from 16 to 0.
Currently there are 6 HDLC protocol drivers, among them:
hdlc_raw_eth, hdlc_cisco, hdlc_ppp, hdlc_x25 set hard_header_len when
attaching the protocol, overriding the default. So this patch does not
affect them.
hdlc_raw and hdlc_fr don't set hard_header_len when attaching the
protocol. So this patch will change the hard_header_len of the HDLC
device for them from 16 to 0.
This is the correct change because both hdlc_raw and hdlc_fr don't have
header_ops, and the code in net/packet/af_packet.c expects the value of
hard_header_len to be consistent with header_ops.
In net/packet/af_packet.c, in the packet_snd function,
for AF_PACKET/DGRAM sockets it would reserve a headroom of
hard_header_len and call dev_hard_header to fill in that headroom,
and for AF_PACKET/RAW sockets, it does not reserve the headroom and
does not call dev_hard_header, but checks if the user has provided a
header of length hard_header_len (in function dev_validate_header).

"port" isn't used again outside this function so I deleted that line.

The VLANs and PVIDs on the RTL8366 utilizes a "member
configuration" (MC) which is largely unexplained in the
code.
This set-up requires a special ordering: rtl8366_set_pvid()
must be called first, followed by rtl8366_set_vlan(),
else the MC will not be properly allocated. Relax this
by factoring out the code obtaining an MC and reuse
the helper in both rtl8366_set_pvid() and
rtl8366_set_vlan() so we remove this strict ordering
requirement.
In the process, add some better comments and debug prints
so people who read the code understand what is going on.

If the partner is busy, the hypervisor will return the H_CLOSED
return code. The aim of this patch is that, if the device is not
ready, to query the device a number of times, with a small wait
time in between queries. If all initialization requests fail,
the driver will remain in a dormant state, awaiting a signal
from the device that it is ready for operation.
