Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Use after free in vlan, from Cong Wang. 2) Handle NAPI poll with a zero budget properly in mlx5 driver, from Saeed Mahameed. 3) If DMA mapping fails in mlx5 driver, NULL out page, from Inbar Karmy. 4) Handle overrun in RX FIFO of sun4i CAN driver, from Gerhard Bertelsmann. 5) Missing return in mdb and vlan prepare phase of DSA layer, from Vivien Didelot. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: vlan: fix a use-after-free in vlan_device_event() net: dsa: return after vlan prepare phase net: dsa: return after mdb prepare phase can: ifi: Fix transmitter delay calculation tcp: fix tcp_fastretrans_alert warning tcp: gso: avoid refcount_t warning from tcp_gso_segment() can: peak: Add support for new PCIe/M2 CAN FD interfaces can: sun4i: handle overrun in RX FIFO can: c_can: don't indicate triple sampling support for D_CAN net/mlx5e: Increase Striding RQ minimum size limit to 4 multi-packet WQEs net/mlx5e: Set page to null in case dma mapping fails net/mlx5e: Fix napi poll with zero budget net/mlx5: Cancel health poll before sending panic teardown command net/mlx5: Loop over temp list to release delay events rds: ib: Fix NULL pointer dereference in debug code
