These checks aren't necessary, cfg80211 never passes NULL.
Some static checkers complain about the missing checks on
the next line, but really the NULL checks are unnecessary.

Pull networking fixes from David Miller:
1) Must perform TXQ teardown before unregistering interfaces in
mac80211, from Toke Høiland-Jørgensen.
2) Don't allow creating mac80211_hwsim with less than one channel, from
Johannes Berg.

Not all SFPs implement the registers containing sensor limits and
alarms. Luckily, there is a bit indicating if they are implemented or
not. Add checking for this bit, when deciding if the hwmon attributes
should be visible.

Recent refactoring of add_metainfo() caused use_all_metadata() to add
metainfo to ife action metalist without taking reference to module. This
causes warning in module_put called from ife action cleanup function.
Implement add_metainfo_and_get_ops() function that returns with reference
to module taken if metainfo was added successfully, and call it from
use_all_metadata(), instead of calling __add_metainfo() directly.
Example warning:

Correct the formula for calculating the RQ page remainder,
which should be in byte granularity. The result will be
non-zero only for RQs smaller than PAGE_SIZE, as an RQ size
is a power of 2.
Divide this by the SQ stride (MLX5_SEND_WQE_BB) to get the
SQ offset in strides granularity.

doing loopback selftest when netdev is down.
This patch fixes it by always preserving vlan 0 in hardware,
because vlan 0 is defalut vlan, which should always be in
hardware.

When ping is runnig and user executes the loopback selftest, the

This patch fixes it by using the hns3_nic_net_open/stop to offline
the netdev when doing loopback selftest.

Tqp and mac need to be enabled when doing loopback selftest,
ae_algo->ops->start/stop is used to do the job, there is a
time window between ae_algo->ops->start/stop and loopback setup,
which will cause selftest failed problem when there is frame
coming in during that time window.
This patch fixes it by enabling the tqp and mac during loopback
setup process.

PF uses hdev->vlan_table to manage the port vlan table. In function
hclge_set_vlan_filter_hw(), it checks whether a vlan id has been used,
by foreach all the vport bits. It should use macro HCLGE_VPORT_NUM,
not VLAN_N_VID as the foreach condition.

There are only 128 entries in vf vlan table, if user has added
more than 128 vlan, fw will ignore it and disable the vf vlan
table. So when user deletes the vlan entry that has not been
set to vf vlan table, fw will return not found result and driver
treat that as error, which will cause vlan delete failed problem.
This patch fixes it by returning ok when fw returns not found
result.

bnxt_en: Bug fixes.
This short series fixes resource related logic in the driver, mostly
affecting the RDMA driver under corner cases.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Currently, the driver adjusts the bp->hw_resc.max_cp_rings by the number
of MSIX vectors used by RDMA. There is one code path in open that needs
to check the true max_cp_rings including any used by RDMA. This code
is now checking for the reduced max_cp_rings which will fail when the
number of cp rings is very small.
To fix this in a clean way, we don't adjust max_cp_rings anymore.
Instead, we add a helper bnxt_get_max_func_cp_rings_for_en() to get the
reduced max_cp_rings when appropriate.

When the driver detects that resources have changed during open, it
should reset the rx and tx rings to 0. This will properly setup the
init sequence to initialize the default rings again. We also need
to signal the RDMA driver to stop and clear its interrupts. We then
call the RoCE driver to restart if a new set of default rings is
successfully reserved.

When users set params.spp_address and get a trans, ipv6_flowlabel flag
should be applied into this trans. But even if this one is not an ipv6
trans, it should not go to apply it into all other transes of the asoc
but simply ignore it.

Now in sctp_apply_peer_addr_params(), if SPP_IPV6_FLOWLABEL flag is set
and trans is NULL, it would use trans as the index variable to traverse
transport_addr_list, then trans is set as the last transport of it.
Later, if SPP_DSCP flag is set, it would enter into the wrong branch as
trans is actually an invalid reference.
So fix it by using a new index variable to traverse transport_addr_list
for both SPP_DSCP and SPP_IPV6_FLOWLABEL flags process.

Currently, tcf_action_delete() nulls actions array pointer after putting

pointer to action is not set to null. That results it being released second
time in error handling code of tca_action_gd().
