mainline inclusion from mainline-master commit 796640778c26f3d99fde173bb7b1d726b5f0d816 category: feature bugzilla: 173966 CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Currently, the driver gets packet type by parsing the L3_ID/L4_ID/OL3_ID/OL4_ID from RX descriptor, it's time-consuming.
Now some new devices support RXD advanced layout, which combines previous OL3_ID/OL4_ID to 8bit ptype field, so the driver gets packet type by looking up only one table, and L3_ID/L4_ID become reserved fields.
Considering compatibility, the firmware will report capability of RXD advanced layout, the driver will identify and enable it by default. This patch provides basic function: identify and enable the RXD advanced layout, and refactor out hns3_rx_checksum() by using ptype table to handle RX checksum if supported.
