Jakub Kicinski ee8b7a1156 net: make drivers set the TSO limit not the GSO limit
Drivers should call the TSO setting helper, GSO is controllable
by user space.

Marcin Kozlowski afb8e24652 net: usb: aqc111: Fix out-of-bounds accesses in RX fixup
aqc111_rx_fixup() contains several out-of-bounds accesses that can be
triggered by a malicious (or defective) USB device, in particular:

 - The metadata array (desc_offset..desc_offset+2*pkt_count) can be out of bounds,
   causing OOB reads and (on big-endian systems) OOB endianness flips.
 - A packet can overlap the metadata array, causing a later OOB
   endianness flip to corrupt data used by a cloned SKB that has already
   been handed off into the network stack.
 - A packet SKB can be constructed whose tail is far beyond its end,
   causing out-of-bounds heap data to be considered part of the SKB's
   data.

Found doing variant analysis. Tested it with another driver (ax88179_178a), since
I don't have a aqc111 device to test it, but the code looks very similar.

Jakub Kicinski 766607570b ethernet: constify references to netdev->dev_addr in drivers
This big patch sprinkles const on local variables and
function arguments which may refer to netdev->dev_addr.

Commit 406f42fa0d ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.

Some of the changes here are not strictly required - const
is sometimes cast off but pointer is not used for writing.
It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled
for the build.

No functional changes.

Igor Russkikh 6ae6d33280 aqc111: cleanup mtu related logic
Original fix b8b277525e was done under impression that invalid data
could be written for mtu configuration higher that 16334.

But the high limit will anyway be rejected my max_mtu check in caller.
Thus, make the code cleaner and allow it doing the configuration without
checking for maximum mtu value.

Oliver Neukum b8b277525e aqc111: fix endianness issue in aqc111_change_mtu
If the MTU is large enough, the first write to the device
is just repeated. On BE architectures, however, the first
word of the command will be swapped a second time and garbage
will be written. Avoid that.
