net: qualcomm: rmnet: Fix incorrect UL checksum offload logic

2019-08-09T15:51:44Z

[ Upstream commit a7cf3d24ee6081930feb4c830a7f6f16ebe31c49 ] The udp_ip4_ind bit is set only for IPv4 UDP non-fragmented packets so that the hardware can flip the checksum to 0xFFFF if the computed checksum is 0 per RFC768. However, this bit had to be set for IPv6 UDP non fragmented packets as well per hardware requirements. Otherwise, IPv6 UDP packets with computed checksum as 0 were transmitted by hardware and were dropped in the network. In addition to setting this bit for IPv6 UDP, the field is also appropriately renamed to udp_ind as part of this change.

net: ethernet: support of_get_mac_address new ERR_PTR error

2019-05-07T19:22:47Z

There was NVMEM support added to of_get_mac_address, so it could now return ERR_PTR encoded error values, so we need to adjust all current users of of_get_mac_address to this new fact. While at it, remove superfluous is_valid_ether_addr as the MAC address returned from of_get_mac_address is always valid and checked by is_valid_ether_addr anyway.

cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37Z

We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out.

net: qualcomm: rmnet: move null check on dev before dereferecing it

Currently dev is dereferenced by the call dev_net(dev) before dev is null checked. Fix this by null checking dev before the potential null pointer dereference.
