The reason is that patch 2 touches some code that has some issues. The issues were not introduced in this patch series. So I prefer to send first the patches to fix those issues which need to go in net and only when those fixes reaches net-next to resend this patch series. Otherwise will be some pretty ugly merge conflicts. So just to make the life easier for everyone, please ignore for now this patch series. > > > Horatiu Vultur (5): > net: lan966x: Add define IFH_LEN_BYTES > net: lan966x: Rename lan966x_fdma_get_max_mtu > net: lan966x: Split function lan966x_fdma_rx_get_frame > net: lan966x: Add basic XDP support > net: lan96x: Use page_pool API > > .../net/ethernet/microchip/lan966x/Kconfig | 1 + > .../net/ethernet/microchip/lan966x/Makefile | 3 +- > .../ethernet/microchip/lan966x/lan966x_fdma.c | 194 +++++++++++------- > .../ethernet/microchip/lan966x/lan966x_ifh.h | 1 + > .../ethernet/microchip/lan966x/lan966x_main.c | 26 ++- > .../ethernet/microchip/lan966x/lan966x_main.h | 28 +++ > .../ethernet/microchip/lan966x/lan966x_xdp.c | 100 +++++++++ > 7 files changed, 275 insertions(+), 78 deletions(-) > create mode 100644 drivers/net/ethernet/microchip/lan966x/lan966x_xdp.c > > -- > 2.38.0 > -- /Horatiu
