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().

2019-03-03dpaa2-eth: add XDP_REDIRECT supportIoana Radulescu
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 Katakam
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.
