[PATCH net-next 0/5] Some cleanup and bugfix for desc filling

[Yunsheng Lin]

When retransmiting packets, skb_cow_head which is called in
hns3_set_tso may clone a new header. And driver will clear the
checksum of the header after doing DMA map, so HW will read the
old header whose L3 checksum is not cleared and calculate a
wrong L3 checksum.

Also When sending a big fragment using multiple buffer descriptor,
hns3 does one maping, but do multiple unmapping when tx is done,
which may cause unmapping problem.

This patchset does some cleanup before fixing the above problem.

Fuyun Liang (3):
  net: hns3: add handling for big TX fragment
  net: hns3: rename hns_nic_dma_unmap
  net: hns3: fix for multiple unmapping DMA problem

Peng Li (2):
  net: hns3: remove hns3_fill_desc_tso
  net: hns3: move DMA map into hns3_fill_desc
