2019-03-03qmi_wwan: Add support for Quectel EG12/EM12Kristian Evensen1-8/+18
Quectel EG12 (module)/EM12 (M.2 card) is a Cat. 12 LTE modem. The modem behaves in the same way as the EP06, so the "set DTR"-quirk must be applied and the diagnostic-interface check performed. Since the diagnostic-check now applies to more modems, I have renamed the function from quectel_ep06_diag_detected() to quectel_diag_detected().

Implement support for the XDP_REDIRECT action. The redirected frame is transmitted and confirmed on the regular Tx/Tx conf queues. Frame is marked with the "XDP" type in the software annotation, since it requires special treatment. We don't have good hardware support for TX batching, so the XDP_XMIT_FLUSH flag doesn't make a difference for now; ndo_xdp_xmit performs the actual Tx operation on the spot.

2019-03-03net: macb: Add support for suspend/resume with full power downHarini Katakam1-2/+38
When macb device is suspended and system is powered down, the clocks are removed and hence macb should be closed gracefully and restored upon resume. This patch does the same by switching off the net device, suspending phy and performing necessary cleanup of interrupts and BDs. Upon resume, all these are reinitialized again. Reset of macb device is done only when GEM is not a wake device. Even when gem is a wake device, tx queues can be stopped and ptp device can be closed (tsu clock will be disabled in pm_runtime_suspend) as wake event detection has no dependency on this.

2019-03-01net: mvpp2: set the GMAC, XLG MAC, XPCS and MPCS in reset when a port is downAntoine Tenart1-0/+3
This patch adds calls in the stop() helper to ensure both MACs and both PCS blocks are set in reset when the user manually sets a port down.

2019-03-01net: mvpp2: set the XPCS and MPCS in reset when not usedAntoine Tenart2-8/+59
This patch sets both the XPCS and MPCS blocks in reset when they aren't used. This is done both at boot time and when reconfiguring a port mode. The advantage now is that only the PCS used is set out of reset when the port is configured (10GKR uses the MCPS while RXAUI uses the XPCS).

2019-03-01net: mvpp2: reset the MACs when reconfiguring a portAntoine Tenart1-0/+3
This patch makes sure both PPv2 MACs (GMAC + XLG MAC) are set in reset while a port is reconfigured. This is done so that we make sure a MAC is in a reset state when not used, as only one of the two will be set out of reset after the port is configured properly.

2019-03-01net: mvpp2: rework the XLG MAC reset handlingAntoine Tenart1-9/+18
This patch reworks the way the XLG MAC is set in reset: the XLG MAC is set in reset at probe time and taken out of this state only when used. The idea is to move forward a situation where only the blocks used are taken out of reset. This also has the effect to handle the GMAC and the XLG MAC in a similar way (the GMAC already is set in reset at boot time). Signed-off-by: Antoine Tenart <[email protected]> Signed-off-by: David S.

2019-03-01net: mvpp2: always disable both MACs when disabling a portAntoine Tenart1-4/+4
This patch modifies the port_disable() helper to always disable both the GMAC and the XLG MAC when called. At boot time we do not know of a port was enabled in the firmware/bootloader, and if so what mode was used (hence which of the two MACs was used). This also help in implementing a logic where all blocks are disabled when not used, and only enabled regarding the current mode used on a given port.

2019-03-01net: mvpp2: some AN fields require the link to be down when updatedAntoine Tenart1-1/+11
The GMAC configuration helper modifies values in the auto-negotiation register. Some of its values require the port to be forced down when modifying their values. This patches fixes the check made on the bit to be updated in this register, so that the port is forced down when needed.

2019-03-01net: mvpp2: fix the computation of the RXQsAntoine Tenart2-10/+17
The patch fixes the computation of RXQs being used by the PPv2 driver, which is set depending on the PPv2 engine version and the queue mode used. There are three cases: - PPv2.1: 1 RXQ per CPU. - PPV2.2 with MVPP2_QDIST_MULTI_MODE: 1 RXQ per CPU. - PPv2.2 with MVPP2_QDIST_SINGLE_MODE: 1 RXQ is shared between the CPUs. The PPv2 engine supports a maximum of 32 queues per port. This patch adds a check so that we do not overstep this maximum. It appeared the calculation was broken for PPv2.1 engines since f8c6ba8424b0, as PPv2.1 ports ended up with a single RXQ while they needed 4. This patch fixes it.
