r8169: fix memory corruption on retrieval of hardware statistics.

2018-01-26T02:34:04+00:00

Hardware statistics retrieval hurts in tight invocation loops.

Avoid extraneous write and enforce strict ordering of writes targeted to
the tally counters dump area address registers.

net/ibm/emac: wrong bit is used for STA control register write

2018-01-24T23:10:57+00:00

STA control register has areas of mode and opcodes for opeations. 18 bit is
using for mode selection, where 0 is old MIO/MDIO access method and 1 is
indirect access mode. 19-20 bits are using for setting up read/write
operation(STA opcodes). In current state 'read' is set into old MIO/MDIO mode
with 19 bit and write operation is set into 18 bit which is mode selection,
not a write operation. To correlate write with read we set it into 20 bit.
All those bit operations are MSB 0 based.

net/ibm/emac: add 8192 rx/tx fifo size

2018-01-24T23:10:57+00:00

emac4syn chips has availability to use 8192 rx/tx fifo buffer sizes,
in current state if we set it up in dts 8192 as example, we will get
only 2048 which may impact on network speed.

i40e: flower: check if TC offload is enabled on a netdev

2018-01-24T21:50:51+00:00

Since TC block changes drivers are required to check if
the TC hw offload flag is set on the interface themselves.

qed: Free reserved MR tid

2018-01-24T21:44:21+00:00

A tid was allocated for reserved MR during initialization but
not freed. This lead to an annoying output message during
rdma unload flow.

mlxsw: spectrum_router: Don't log an error on missing neighbor

2018-01-24T15:58:22+00:00

Driver periodically samples all neighbors configured in device
in order to update the kernel regarding their state. When finding
an entry configured in HW that doesn't show in neigh_lookup()
driver logs an error message.
This introduces a race when removing multiple neighbors -
it's possible that a given entry would still be configured in HW
as its removal is still being processed but is already removed
from the kernel's neighbor tables.

Simply remove the error message and gracefully accept such events.

be2net: restore properly promisc mode after queues reconfiguration

2018-01-22T21:22:42+00:00

The commit 622190669403 ("be2net: Request RSS capability of Rx interface
depending on number of Rx rings") modified be_update_queues() so the
IFACE (HW representation of the netdevice) is destroyed and then
re-created. This causes a regression because potential promiscuous mode
is not restored properly during be_open() because the driver thinks
that the HW has promiscuous mode already enabled.

Note that Lancer is not affected by this bug because RX-filter flags are
disabled during be_close() for this chipset.

ibmvnic: Allocate and request vpd in init_resources

2018-01-22T20:46:55+00:00

In reset events in which our memory allocations need to be reallocated,
VPD data is being freed, but never reallocated. This can cause issues if
we later attempt to access that memory or reset and attempt to free the
memory. This patch moves the allocation of the VPD data to init_resources
so that it will be symmetrically freed during release resources.

ibmvnic: Revert to previous mtu when unsupported value requested

2018-01-22T20:46:55+00:00

If we request an unsupported mtu value, the vnic server will suggest a
different value. Currently we take the suggested value without question
and login with that value. However, the behavior doesn't seem completely
sane as attempting to change the mtu to some specific value will change
the mtu to some completely different value most of the time. This patch
fixes the issue by logging in with the previously used mtu value and
printing an error message saying that the given mtu is unsupported.
