Tested on the Macchiatobin eth1 port. Note that on the Macchiatobin, eth0 uses a separate TAI block from eth1, and there is no hardware synchronisation between the two. drivers/net/ethernet/marvell/Kconfig | 6 + drivers/net/ethernet/marvell/mvpp2/Makefile | 3 +- drivers/net/ethernet/marvell/mvpp2/mvpp2.h | 202 ++++++++++- drivers/net/ethernet/marvell/mvpp2/mvpp2_main.c | 410 ++++++++++++++++++--- drivers/net/ethernet/marvell/mvpp2/mvpp2_tai.c | 457 ++++++++++++++++++++++++ 5 files changed, 1028 insertions(+), 50 deletions(-) create mode 100644 drivers/net/ethernet/marvell/mvpp2/mvpp2_tai.c v2: add Andrew's r-bs, squash patch 6 and patch 7. v3: Address Richard's comments on patch 4. v4: replace fixes from v2.
