qlge: Fix netdev features configuration.

2018-08-26T00:37:38+00:00

qlge_fix_features() is not supposed to modify hardware or
driver state, rather it is supposed to only fix requested
fetures bits. Currently qlge_fix_features() also goes for
interface down and up unnecessarily if there is not even
any change in features set.

This patch changes/fixes following -

1) Move reload of interface or device re-config from
   qlge_fix_features() to qlge_set_features().
2) Reload of interface in qlge_set_features() only if
   relevant feature bit (NETIF_F_HW_VLAN_CTAG_RX) is changed.
3) Get rid of qlge_fix_features() since driver is not really
   required to fix any features bit.

net: macb: do not disable MDIO bus at open/close time

2018-08-26T00:34:48+00:00

macb_reset_hw() is called from macb_close() and indirectly from
macb_open(). macb_reset_hw() zeroes the NCR register, including the MPE
(Management Port Enable) bit.

This will prevent accessing any other PHYs for other Ethernet MACs on
the MDIO bus, which remains registered at macb_reset_hw() time, until
macb_init_hw() is called from macb_open() which sets the MPE bit again.

I.e. currently the MDIO bus has a short disruption at open time and is
disabled at close time until the interface is opened again.

Fix that by only touching the RE and TE bits when enabling and disabling
RX/TX.

v2: Make macb_init_hw() NCR write a single statement.

This reverts commit bde4975310eb1982bd0bbff673989052d92fd481.

All legacy clock implementations now implement clk_set_rate() (Some
implementations may be dummies, though).

net: macb: Fix regression breaking non-MDIO fixed-link PHYs

2018-08-26T00:30:02+00:00

commit 739de9a1563a ("net: macb: Reorganize macb_mii bringup") broke
initializing macb on the EVB-KSZ9477 eval board.
There, of_mdiobus_register was called even for the fixed-link representing
the RGMII-link to the switch with the result that the driver attempts to
enumerate PHYs on a non-existent MDIO bus:

	libphy: MACB_mii_bus: probed
	mdio_bus f0028000.ethernet-ffffffff: fixed-link has invalid PHY address
	mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 0
        [snip]
	mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 31

The "MDIO" bus registration succeeds regardless, having claimed the reset GPIO,
and calling of_phy_register_fixed_link later on fails because it tries
to claim the same GPIO:

	macb f0028000.ethernet: broken fixed-link specification

Fix this by registering the fixed-link before calling mdiobus_register.

mlxsw: spectrum_switchdev: Do not leak RIFs when removing bridge

2018-08-25T23:28:20+00:00

When a bridge device is removed, the VLANs are flushed from each
configured port. This causes the ports to decrement the reference count
on the associated FIDs (filtering identifier). If the reference count of
a FID is 1 and it has a RIF (router interface), then this RIF is
destroyed.

However, if no port is member in the VLAN for which a RIF exists, then
the RIF will continue to exist after the removal of the bridge. To
reproduce:

# ip link add name br0 type bridge vlan_filtering 1
# ip link set dev swp1 master br0
# ip link add link br0 name br0.10 type vlan id 10
# ip address add 192.0.2.0/24 dev br0.10
# ip link del dev br0

The RIF associated with br0.10 continues to exist.

Fix this by iterating over all the bridge device uppers when it is
destroyed and take care of destroying their RIFs.

i40e: fix condition of WARN_ONCE for stat strings

2018-08-24T15:52:35+00:00

Commit 9b10df596bd4 ("i40e: use WARN_ONCE to replace the commented
BUG_ON size check") introduced a warning check to make sure
that the size of the stat strings was always the expected value. This
code accidentally inverted the check of the data pointer. Fix this so
that we accurately count the size of the stats we copied in.

This fixes an erroneous WARN kernel splat that occurs when requesting
ethtool statistics.

i40e: Fix for Tx timeouts when interface is brought up if DCB is enabled

2018-08-24T15:52:35+00:00

If interface is connected to switch port configured for DCB there are
TX timeouts when bringing up interface. Problem started appearing after
adding in i40e driver code mqprio hardware offload mode. In function
i40e_vsi_configure_bw_alloc was added resetting BW rate which should
be executing when mqprio qdisc is removed but was also when there was
no mqprio qdisc added and DCB was enabled. In this patch was added
additional check for DCB flag so now when DCB is enabled the correct
DCB configs from before mqprio patch are restored.
