In our Fuz testing, reference client corrupts the dest mac to "00:00:00:00:00:00"
in the WPA2 handshake no 2. During driver init the sta_list entries mac
addresses are by default "00:00:00:00:00:00". Driver returns an invalid
pointer (conn) and the drver shall crash, if rxtids (aggr_conn)
skb queues are accessed, since they would not be initialized.

By default the SoC PS option is disabled to boost the

Both [eTSEC76] and [eTSEC12] errata relate to Tx checksum generation
(for some MPC83xx and MCP8548 older revisions). They require the same
workaround: manual checksum computation and insertion, and disabling
the H/W Tx csum acceleration feature (per frame) through Tx FCB
(Frame Control Block) csum offload settings.
The workaround for [eTSEC76] needs to be fixed because it currently
fails to disable H/W Tx csum insertion via FCB. This patch fixes it
and provides a common workaround implementation for both Tx csum errata.

We're already protected by RTNL lock, so nothing can happen to bond/its

Also, add ASSERT_RTNL() both to bond_set_rx_mode() and bond_hw_addr_swap()
to catch possible uses of it without RTNL locking.
This patch also saves us from a lockdep false-positive in
bond_set_rx_mode() vs bond_hw_addr_swap().

Currently we use a lot of time comparison math for arp_interval
comparisons, which are sometimes quite hard to read and understand.
All the time comparisons have one pattern:
(time - arp_interval_jiffies) <= jiffies <= (time + mod *
arp_interval_jiffies + arp_interval_jiffies/2)
Introduce a new helper - bond_time_in_interval(), which will do the math in
one place and, thus, will clean up the logical code. This helper introduces
a bit of overhead (by always calculating the jiffies from arp_interval),
however it's really not visible, considering that functions using it
usually run once in arp_interval milliseconds.
There are several lines slightly over 80 chars, however breaking them would
result in more hard-to-read code than several character after the 80 mark.

This fixes interrupt-related issue when no
interfaces were running thus the device was
considered powered down.
The power_down() function isn't really powering
down the device. It simply assumed it won't
interrupt. This wasn't true in some cases and
could lead to paging failures upon FW indication
interrupt (i.e. FW crash) because some structures
aren't allocated in that device state.
One reason for that was that ar_pci->started
wasn't reset. The other is interrupts should've
been masked when teardown starts.
The patch reorganized interrupt setup and makes
sure ar_pci->started is reset accordingly.
