[PATCH 26/37] docs: networking: device drivers: convert microsoft/netvsc.txt to ReST

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



- add SPDX header;
- adjust titles and chapters, adding proper markups;
- mark code blocks and literals as such;
- adjust identation, whitespaces and blank lines where needed;
- add to networking/index.rst.

+Checksum offload
+----------------
   The netvsc driver supports checksum offload as long as the
   Hyper-V host version does. Windows Server 2016 and Azure
   support checksum offload for TCP and UDP for both IPv4 and
   IPv6. Windows Server 2012 only supports checksum offload for TCP.

   The driver supports GRO and it is enabled by default. GRO coalesces

   The driver supports LRO/RSC in the vSwitch feature. It reduces the per packet
