The MC8305 module got an additional entry added based solely on
information from a Windows driver *.inf file. We now have the
actual descriptor layout from one of these modules, and it
consists of two alternate configurations where cfg #1 is a
normal Gobi 2k layout and cfg #2 is MBIM only, using interface
numbers 5 and 6 for MBIM control and data. The extra Windows
driver entry for interface number 5 was most likely a bug.

Deleting the bogus entry to avoid unnecessary qmi_wwan probe
failures when using the MBIM configuration.

This patch fixed that enh_desc value is always zero.
Due to calling order of stmmac_selec_desc_mode(), enh_desc value is always zero.
Even though mac is set to use enhanced dma descriptor, if enh_desc is zero,
functions related dma descriptor are not working correctly.

Within VST mode, enable modifying the vlan and/or qos
for a VF without requiring unbind/rebind.

This requires firmware which supports the UPDATE_QP command.
(If the command is not available, we fall back to requiring
unbind/bind to activate these changes).

To avoid race conditions with modify-qp on QPs that are affected
by update-qp, this operation is performed on the comm_wq.

If the update operation succeeds for all the necessary QPs, a
vlan_unregister is performed for the abandoned vlan id.

This patch fixes the following warning introduced in e4fc408e
("packet: nlmon: virtual netlink monitoring device for packet
sockets") reported by Dan Carpenter:

warning: "drivers/net/nlmon.c:31 nlmon_is_valid_mtu()
	 warn: always true condition '(new_mtu <= ((~0 >> 1))) =>
				      (s32min-s32max <= s32max)'"

Thus, we should simply remove the test against INT_MAX. Next to that
we also need to explicitly cast the sizeof() case as the comparison
is type promoted to unsigned long so negative values are then
valid instead of invalid. While at it, this also adds a comment about
Netlink and MTUs.

A simple semantic change, when a slave's MAC is cloned by the bond
master then set addr_assign_type to NET_ADDR_STOLEN instead of
NET_ADDR_SET. Also use bond_set_dev_addr() in BOND_FOM_ACTIVE mode
to change the bond's MAC address because the assign_type has to be
set properly.

In struct bonding there's a member called dev_addr_from_first which is
used to denote when the bond dev should clone the first slave's MAC
address but since we have netdev's addr_assign_type variable that is not
necessary. We clone the first slave's MAC each time we have a random MAC
set to the bond device. This has the nice side-effect of also fixing an
inconsistency - when the MAC address of the bond dev is set after its
creation, but prior to having slaves, it's not kept and the first slave's
MAC is cloned. The only way to keep the MAC was to create the bond device
with the MAC address set (e.g. through ip link). In all cases if the
bond device is left without any slaves - its MAC gets reset to a random
one as before.

We have a member called setup_by_slave in struct bonding to denote if the

Transmit packets needs to be tagged in order to receive a tx status
feedback from the firmware. Determine the tag in the netdev transmit
callback instead of determining the tag just before transfer to the
device. This reduces the number of exception flows and hence makes
