Qlogic's 82xx series adapter doesn't support
tunnel offloads, driver incorrectly assumes that it is
supported and causes firmware hang while running tunnel IO.
This patch fixes this by not advertising tunnel offloads
for 82xx adapters.

qlcnic_82xx_hw_read_wx_2M
The driver may sleep under a write spin lock, and the function
call path is:
qlcnic_82xx_hw_write_wx_2M (acquire the lock by write_lock_irqsave)
crb_win_lock
qlcnic_pcie_sem_lock
usleep_range
qlcnic_82xx_hw_read_wx_2M (acquire the lock by write_lock_irqsave)
crb_win_lock
qlcnic_pcie_sem_lock
usleep_range
To fix it, the usleep_range is replaced with udelay.

Currently driver returns error on speed configurations
for 83xx adapter's non XGBE ports, due to this link doesn't
come up on the ports using 1000Base-T as a connector with
autoneg disabled. This patch fixes this with initializing
appropriate port type based on queried module/connector
types from hardware before any speed/autoneg configuration.

Introduce new rtnl UAPI that exposes a list of vlans per VF, giving
the ability for user-space application to specify it for the VF, as an
option to support 802.1ad.
We adjusted IP Link tool to support this option.
For future use cases, the new UAPI supports multiple vlans. For now we
limit the list size to a single vlan in kernel.
Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward
compatibility with older versions of IP Link tool.
Add a vlan protocol parameter to the ndo_set_vf_vlan callback.
We kept 802.1Q as the drivers' default vlan protocol.
Suitable ip link tool command examples:
Set vf vlan protocol 802.1ad:
ip link set eth0 vf 1 vlan 100 proto 802.1ad
Set vf to VST (802.1Q) mode:
ip link set eth0 vf 1 vlan 100 proto 802.1Q
Or by omitting the new parameter
ip link set eth0 vf 1 vlan 100

fdb dumps spanning multiple skb's currently restart from the first
interface again for every skb. This results in unnecessary
iterations on the already visited interfaces and their fdb
entries. In large scale setups, we have seen this to slow
down fdb dumps considerably. On a system with 30k macs we
see fdb dumps spanning across more than 300 skbs.
To fix the problem, this patch replaces the existing single fdb
marker with three markers: netdev hash entries, netdevs and fdb
index to continue where we left off instead of restarting from the
first netdev. This is consistent with link dumps.
In the process of fixing the performance issue, this patch also
re-implements fix done by
commit 472681d57a5d ("net: ndo_fdb_dump should report -EMSGSIZE to rtnl_fdb_dump")
(with an internal fix from Wilson Kok) in the following ways:
- change ndo_fdb_dump handlers to return error code instead
of the last fdb index
- use cb->args strictly for dump frag markers and not error codes.
This is consistent with other dump functions.
Below results were taken on a system with 1000 netdevs
and 35085 fdb entries:
before patch:
$time bridge fdb show | wc -l
15065
real 1m11.791s
user 0m0.070s
sys 1m8.395s
(existing code does not return all macs)
after patch:
$time bridge fdb show | wc -l
35085
real 0m2.017s
user 0m0.113s
sys 0m1.942s

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.

and it receives a spurious MB interrupt, it is mistaken as a good MB

The bonding driver saves a copy of slaves' original mac address and then
assigns whatever mac as needed to the slave, depending on mode. In at
least modes 5 and 6 (balance-tlb, balance-alb), it often ends up being the
mac address of another slave. On release from the bond, the original mac
address is supposed to get restored via a dev_set_mac_address() call in
the bonding driver's __bond_release_one() function, which calls the
slave's ndo_set_mac_address function, which for qlcnic, is
qlcnic_set_mac().
Now, this function tries to be somewhat intelligent and exit early if
you're trying to set the mac address to the same thing that is already
set. The problem here is that adapter->mac_addr isn't in sync with
netdev->dev_addr. The qlcnic driver still has the original mac stored in
adapter->mac_addr, while the bonding driver has updated netdev->dev_addr,
so qlcnic thinks we're trying to set the same address it already has.
I think the way to go here, since the function updates both netdev and
adapter's stored mac addresses, is to check if either of them doesn't
match the newly requested mac. Simply checking netdev's value only could
result in a similar mismatch and non-update, so look at both.
