New 7.0 FW: bnx2x, cnic, bnx2i, bnx2fc

New FW/HSI (7.0):
 - Added support to 578xx chips
 - Improved HSI - much less driver's direct access to the FW internal
   memory needed.

New implementation of the HSI handling layer in the bnx2x (bnx2x_sp.c):
 - Introduced chip dependent objects that have chip independent interfaces
   for configuration of MACs, multicast addresses, Rx mode, indirection table,
   fast path queues and function initialization/cleanup.
 - Objects functionality is based on the private function pointers, which
   allows not only a per-chip but also PF/VF differentiation while still
   preserving the same interface towards the driver.
 - Objects interface is not influenced by the HSI changes which do not require
   providing new parameters keeping the code outside the bnx2x_sp.c invariant
   with regard to such HSI chnages.

snmp: reduce percpu needs by 50%

SNMP mibs use two percpu arrays, one used in BH context, another in USER
context. With increasing number of cpus in machines, and fact that ipv6
uses per network device ipstats_mib, this is consuming a lot of memory
if many network devices are registered.

commit be281e554e2a (ipv6: reduce per device ICMP mib sizes) shrinked
percpu needs for ipv6, but we can reduce memory use a bit more.

With recent percpu infrastructure (irqsafe_cpu_inc() ...), we no longer
need this BH/USER separation since we can update counters in a single
x86 instruction, regardless of the BH/USER context.

Other arches than x86 might need to disable irq in their
irqsafe_cpu_inc() implementation : If this happens to be a problem, we
can make SNMP_ARRAY_SZ arch dependent, but a previous poll
( https://lkml.org/lkml/2011/3/17/174 ) to arch maintainers did not
raise strong opposition.

Only on 32bit arches, we need to disable BH for 64bit counters updates
done from USER context (currently used for IP MIB)

This also reduces vmlinux size :

e1000e: Clear host wakeup bit on 82577/8 without touching PHY page 800

The Host Wakeup Active bit in the PHY Port General Configuration register
(page 769 register 17) must be cleared after every PHY reset to prevent an
unexpected wake signal from the PHY. Originally, this was accomplished by
simply reading the PHY Wakeup Control register on page 800 which clears the
Host Wakeup Active bit as a side-effect. Unfortunately, a hardware bug on
the 82577 and 82578 PHY can cause unexpected behavior when registers on
page 800 are accessed while in gigabit mode.

This patch changes the remaining instances when the Host Wakeup Active bit
needs to be cleared while possibly in gigabit mode by accessing the Port
General Configuration register directly instead of accessing any register
on page 800.

e1000e: access multiple PHY registers on same page at the same time

Doing a PHY page select can take a long time, relatively speaking. This
can cause a significant delay when updating a number of PHY registers on
the same page by unnecessarily setting the page for each PHY access. For
example when going to Sx, all the PHY wakeup registers (WUC, RAR[], MTA[],
SHRAR[], IP4AT[], IP6AT[], etc.) on 82577/8/9 need to be updated which
takes a long time which can cause issues when suspending.

This patch introduces new PHY ops function pointers to allow callers to
set the page directly and do any number of PHY accesses on that page.
This feature is currently only implemented for 82577, 82578 and 82579
PHYs for both the normally addressed registers as well as the special-
case addressing of the PHY wakeup registers on page 800. For the latter
registers, the existing function for accessing the wakeup registers has
been divided up into three- 1) enable access to the wakeup register page,
2) perform the register access and 3) disable access to the wakeup register
page. The two functions that enable/disable access to the wakeup register
page are necessarily available to the caller so that the caller can restore
the value of the Port Control (a.k.a. Wakeup Enable) register after the
wakeup register accesses are done.

All instances of writing to multiple PHY registers on the same page are
updated to use this new method and to acquire any PHY locking mechanism
before setting the page and performing the register accesses, and release
the locking mechanism afterward.

Some affiliated magic number cleanup is done as well.

e1000e: 82579 intermittently disabled during S0->Sx

When repeatedly cycling Sx->S0 states with the network cable unplugged,
the 82579 PHY may not initialize as expected and may require a full power
cycle to recover functionality to the device.  Workaround this by testing

This is implemented in the new function e1000_resume_workarounds_pchlan()

If the FELB is activated, the SerDes link becomes non-functional and must

bonding:delete agg_select_mode from ad_bond_info

bond_params->ad_select and ad_bond_info->agg_select_mode have the same

__get_agg_selection_mode() get ad_select from bond_params directly.
