net: mvpp2x: Set BM poll size once during priv probe

2017-08-10T06:33:02Z

Set BM poll size once during priv probe and do not overwrite it during port probe procedure. Pool is common for all CP ports. Signed-off-by: Stefan Chulski Tested-by: iSoC Platform CI Reviewed-by: Nadav Haklai Reviewed-by: Igal Liberman Acked-by: Joe Hershberger Signed-off-by: Stefan Roese

net: mvpp2x: remove TX drain from transmit routine

2017-08-10T06:33:02Z

TX drain in transmit procedure could cause issues due to race between drain procedure and transmition of descriptor between AGGR TXQ and physical TXQ. TXQ will be cleared before moving to Linux by stop procedure.

net: mvpp2x: Remove IRQ configuration from U-Boot

2017-08-10T06:33:02Z

Remove IRQ configuration from U-Boot PP driver. U-Boot don't use interrupts and configuration of IRQ in U-Boot caused crashes in Linux shared interrupt mode. Also interrupt use is redundant in RX routine since a single RX queue is used.

net: mvpp2x: decrease size of AGGR_TXQ and CPU_DESC_CHUNK

2017-08-10T06:33:02Z

U-boot use single physical tx queue with size 16 descriptors. So aggregated tx queue size should be equal to physical tx queue and cpu descriptor chunk(number of descriptors delivered from physical tx queue to aggregated tx queue by one chunk) shouldn't be larger than physical tx queue. Fix: Set AGGR_TXQ and CPU_DESC_CHUNK to be 16 descriptors, same as physical TXQ.

net: mvpp2x: fix BM configuration overrun issue

2017-08-10T06:33:02Z

Issue: BM counters were overrun by probe that called per Network interface and caused release of wrong number of buffers during remove procedure. Fix: Use probe_done and num_ports to call init and remove procedure once per communication controller.

This patch enables padding of packets shorter than 64B in TX(set by default). Disabling of padding causes crashes on MACCIATO board. Signed-off-by: Stefan Chulski Tested-by: iSoC Platform CI Reviewed-by: Igal Liberman Acked-by: Joe Hershberger Signed-off-by: Stefan Roese

net: mvpp2x: fix phy connected to wrong mdio issue

2017-08-10T06:33:02Z

A8K marvell SoC has two South Bridge communication controllers(CP0 and CP1). Each communication controller has packet processor ports and MDIO. On MACHIATOBin board ports from CP1 are connected to mdio on CP0. Issue: Wrong base address is assigned to MDIO interface during probe. Fix: Get MDIO address from PHY handler parent base address. This should be refined in the future when MDIO driver is implemented.
