xen-netback: correct success/error reporting for the SKB-with-fraglist case

2021-10-09T12:40:56+00:00

[ Upstream commit 3ede7f84c7c21f93c5eac611d60eba3f2c765e0f ]

When re-entering the main loop of xenvif_tx_check_gop() a 2nd time, the
special considerations for the head of the SKB no longer apply. Don't
mistakenly report ERROR to the frontend for the first entry in the list,
even if - from all I can tell - this shouldn't matter much as the overall
transmit will need to be considered failed anyway.

net: mdio: introduce a shutdown method to mdio device drivers

2021-10-09T12:40:56+00:00

[ Upstream commit cf9579976f724ad517cc15b7caadea728c7e245c ]

MDIO-attached devices might have interrupts and other things that might
need quiesced when we kexec into a new kernel. Things are even more
creepy when those interrupt lines are shared, and in that case it is
absolutely mandatory to disable all interrupt sources.

Moreover, MDIO devices might be DSA switches, and DSA needs its own
shutdown method to unlink from the DSA master, which is a new
requirement that appeared after commit 2f1e8ea726e9 ("net: dsa: link
interfaces with the DSA master to get rid of lockdep warnings").

So introduce a ->shutdown method in the MDIO device driver structure.

usb: hso: remove the bailout parameter

2021-10-06T13:56:02+00:00

commit dcb713d53e2eadf42b878c12a471e74dc6ed3145 upstream.

There are two invocation sites of hso_free_net_device. After
refactoring hso_create_net_device, this parameter is useless.
Remove the bailout in the hso_free_net_device and change the invocation
sites of this function.

net: phy: bcm7xxx: Fixed indirect MMD operations

2021-10-06T13:55:58+00:00

[ Upstream commit d88fd1b546ff19c8040cfaea76bf16aed1c5a0bb ]

When EEE support was added to the 28nm EPHY it was assumed that it would
be able to support the standard clause 45 over clause 22 register access
method. It turns out that the PHY does not support that, which is the
very reason for using the indirect shadow mode 2 bank 3 access method.

Implement {read,write}_mmd to allow the standard PHY library routines
pertaining to EEE querying and configuration to work correctly on these
PHYs. This forces us to implement a __phy_set_clr_bits() function that
does not grab the MDIO bus lock since the PHY driver's {read,write}_mmd
functions are always called with that lock held.

net: hns3: fix always enable rx vlan filter problem after selftest

2021-10-06T13:55:58+00:00

[ Upstream commit 27bf4af69fcb9845fb2f0076db5d562ec072e70f ]

Currently, the rx vlan filter will always be disabled before selftest and
be enabled after selftest as the rx vlan filter feature is fixed on in
old device earlier than V3.

However, this feature is not fixed in some new devices and it can be
disabled by user. In this case, it is wrong if rx vlan filter is enabled
after selftest. So fix it.

net: hns3: fix show wrong state when add existing uc mac address

2021-10-06T13:55:57+00:00

[ Upstream commit 108b3c7810e14892c4a1819b1d268a2c785c087c ]

Currently, if function adds an existing unicast mac address, eventhough
driver will not add this address into hardware, but it will return 0 in
function hclge_add_uc_addr_common(). It will cause the state of this
unicast mac address is ACTIVE in driver, but it should be in TO-ADD state.

To fix this problem, function hclge_add_uc_addr_common() returns -EEXIST
if mac address is existing, and delete two error log to avoid printing
them all the time after this modification.

net: hns3: fix mixed flag HCLGE_FLAG_MQPRIO_ENABLE and HCLGE_FLAG_DCB_ENABLE

[ Upstream commit 0472e95ffeac8e61259eec17ab61608c6b35599d ]

HCLGE_FLAG_MQPRIO_ENABLE is supposed to set when enable
multiple TCs with tc mqprio, and HCLGE_FLAG_DCB_ENABLE is
supposed to set when enable multiple TCs with ets. But
the driver mixed the flags when updating the tm configuration.

Furtherly, PFC should be available when HCLGE_FLAG_MQPRIO_ENABLE
too, so remove the unnecessary limitation.
