Bert Kenward a995560a27 sfc: use new performance based event queue init
Rather than explicitly specifying flags we can now specify a desired
performance target to the firmware, ie higher throughput or lower latency.
For now we use the default "auto" configuration.

The interface would not function after the system had been woken up

reason for this is that all device registers have been reset to its
default values. This patch adds sleep suspend and resume functions that
detached the interface at suspend and restore the registers and reattach
the interface at resume.

Only the registers that are only configured at probe time needs to be
explicitly restored by the resume handler. All other registers are
reconfigured by either reopening the device in the resume handler (if
the device was running when the system was suspended) or when the
interface is opened by a user at a later time.

Grygorii Strashko aeec302104 net: ethernet: ti: cpdma: remove used_desc counter
The struct cpdma_desc_pool->used_desc field can be safely removed from
CPDMA driver (and hot patch) because used_descs counter is used just
for pool consistency check at CPDMA deinitialization and now this
check can be re-implemnted using gen_pool_size(pool->gen_pool) !=
gen_pool_avail(pool->gen_pool).
More over, this will allow to get rid of warnings in
cpdma_desc_pool_destro()-> WARN_ON(pool->used_desc) which may happen
because the used_descs is used unprotected, since CPDMA has been
switched to use genalloc, and may get wrong values on SMP.

Hence, remove used_desc from struct cpdma_desc_pool.

Sathya Perla b71724147e be2net: replace polling with sleeping in the FW completion path
The ndo_set_rx_mode() and ndo_add/del_vxlan_port() calls may be called with
BHs disabled. The driver currently issues the required cmds to the FW in
these contexts and polls on completions from the FW, while BHs remain
disabled.  This can cause either packet loss or packet reception to be
delayed on that CPU.

This patch defers processing of the above cmds to a separate workqueue.
With this change, FW cmds are now issued only in process context.
Now that the FW cmds are issued only in process context, they can sleep
waiting for a completion instead of polling. All the spin_lock_bh(mcc_lock)
calls are now replaced with mutex calls.

Also a new rx_filter_lock is now needed to protect the RX filtering fields
like vids[] between be_vlan_add/rem_vid() and __be_set_rx_mode() contexts.

Sriharsha Basavapatna 92fbb1df83 be2net: Avoid unnecessary firmware updates of multicast list
Eachtime the ndo_set_rx_mode() routine is called, the driver programs the
multicast list in the adapter without checking if there are any changes to
the list. This leads to a flood of RX_FILTER cmds when a number of vlan
interfaces are configured over the device, as the ndo_ gets
called for each vlan interface. To avoid this, we now use __dev_mc_sync()
and __dev_uc_sync() API, but only to detect if there is a change in the
mc/uc lists. Now that we use this API, the code has to be-designed to
issue these API calls for each invocation of the be_set_rx_mode() call.

Manish Chopra 2b10d3ecf2 qlcnic: fix data structure corruption in async mbx command handling
This patch fixes a data structure corruption bug in the SRIOV VF mailbox
handler code. While handling mailbox commands from the atomic context,
driver is accessing and updating qlcnic_async_work_list_struct entry fields
in the async work list. These fields could be concurrently accessed by the
work function resulting in data corruption.

This patch restructures async mbx command handling by using a separate
async command list instead of using a list of work_struct structures.
A single work_struct is used to schedule and handle the async commands
with proper locking mechanism.
