Commit 60e453a940 ("USBNET: fix handling padding packet")

failed to update the initialisation of the list. This can
cause list traversal to fall off the end of the list,

sh_eth_error() in case of a TX error tries to print a message using 2 dev_err()
calls with the first string not finished by '\n', so that the resulting message
would inevitably come out garbled, with something like "3net eth0: " inserted
in the middle. Avoid that by merging 2 calls into one.
While at it, insert an empty line after the nearby declaration.

Currently, the implementation is meaningless - once again, we take the

Fix this by removing the rcu_read_lock() from __get_active_agg(), and

Currently, the RCU read lock usage is just wrong - it gets the slave struct
under RCU and continues to use it when RCU lock is released.
However, it's still safe to do this cause we didn't need the
rcu_read_lock() initially - all of the __get_first_agg() callers are either
holding RCU read lock or the RTNL lock, so that we can't sync while in it.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates
This series contains updates to i40e and now i40evf.
Most notable is Jacob's patch to add PTP support to i40e.
Mitch cleans up additional memcpy's and use struct assignment instead.
Then fixes long lines to appease checkpatch.pl. Mitch then provides
a fix to keep us from spamming the log with confusing errors. If you
use ip to change the MAC address of a VF while the VF driver is loaded,
closing the VF interface or unloading the VF driver will cause the VF
driver to remove the MAC filter for its original (now invalid) MAC
address.
Jesse cleans up macros which are no longer needed or used.
I (Jeff) cleanup function header comments to ensure Doxygen/kdoc works
correctly to generate documentation without warnings.
Anjali fixes a bug where ethtool set-channels would return failure when
configuring only one Rx queue. Then fixes a bug where the driver was
erroneously exiting the driver unload path if one part of the unload
failed.
Shannon fixes if the IPV6EXADD but is set in the Rx descriptor status,
there was an optional extension header with an alternate IP address
detected and the hardware checksum was not handling the alternate IP
address correctly. Then adjusts the ITR max and min values to match
the hardware max value and recommended min value. Shannon makes sure
to clear the PXE mode after the adminq is initialized.
v2:
- fix patch 14 "i40e: enable PTP" to address Richard Cochran's spelling
catch and Ben Hutchings Kconfig, SIOCGHWTSTAMP and sizeof() suggestions
- added Paul Gortmaker's i40evf fix patch
v3:
- fix patch 14 "i40e: enable PTP" to address Ben Hutchings concerns about
a race with PTP init and cleanup and i40e_get_ts_info().

If the IPV6EXADD bit is set in the Rx descriptor status, there
was an optional extension header with an alternate IP address
detected. The HW checksum offload doesn't handle the alternate
IP address correctly so likely comes up with the wrong answer.
Thus, if the bit is set we ignore the checksum offload value.

If you use ip to change the MAC address of a VF while the VF
driver is loaded, closing the VF interface or unloading the VF
driver will cause the VF driver to remove the MAC filter for its
original (now invalid) MAC address. This would cause the PF
driver to kick an error message to the log, and back to the VF
driver.
Since the VF driver has not really done anything naughty, let's
not punish it. Don't check for MAC address overrides on the
delete operation, just make sure it's a valid address. This keeps
us from spamming the log with confusing errors.
