net: mvmdio: disable/unprepare clocks in EPROBE_DEFER case

2018-01-02T19:04:58+00:00

[ Upstream commit 589bf32f09852041fbd3b7ce1a9e703f95c230ba ]

add appropriate calls to clk_disable_unprepare() by jumping to out_mdio
in case orion_mdio_probe() returns -EPROBE_DEFER.

tg3: Fix rx hang on MTU change with 5717/5719

2018-01-02T19:04:58+00:00

[ Upstream commit 748a240c589824e9121befb1cba5341c319885bc ]

This fixes a hang issue seen when changing the MTU size from 1500 MTU
to 9000 MTU on both 5717 and 5719 chips. In discussion with Broadcom,
they've indicated that these chipsets have the same phy as the 57766
chipset, so the same workarounds apply. This has been tested by IBM
on both Power 8 and Power 9 systems as well as by Broadcom on x86
hardware and has been confirmed to resolve the hang issue.

fm10k: ensure we process SM mbx when processing VF mbx

2017-12-25T13:20:09+00:00

[ Upstream commit 17a91809942ca32c70026d2d5ba3348a2c4fdf8f ]

When we process VF mailboxes, the driver is likely going to also queue
up messages to the switch manager. This process merely queues up the
FIFO, but doesn't actually begin the transmission process. Because we
hold the mailbox lock during this VF processing, the PF<->SM mailbox is
not getting processed at this time. Ensure that we actually process the
PF<->SM mailbox in between each PF<->VF mailbox.

This should ensure prompt transmission of the messages queued up after
each VF message is received and handled.

Check memory allocation failures and return -ENOMEM in such cases, as
already done for other memory allocations in this function.

This avoids NULL pointers dereference.

i40e: Do not enable NAPI on q_vectors that have no rings

2017-12-25T13:20:08+00:00

[ Upstream commit 13a8cd191a2b470cfd435b3b57dbd21aa65ff78c ]

When testing the epoll w/ busy poll code I found that I could get into a
state where the i40e driver had q_vectors w/ active NAPI that had no rings.
This was resulting in a divide by zero error.  To correct it I am updating
the driver code so that we only support NAPI on q_vectors that have 1 or
more rings allocated to them.
