WFP engine is not honoring FWP_CALLOUT_FLAG_ALLOW_RSC flag. RRS feed

  • Question

  • Hi,

    https://msdn.microsoft.com/library/windows/hardware/hh439700(v=vs.85) link says,  If FWP_CALLOUT_FLAG_ALLOW_RSC flag is not specified, and a callout is registered, then RSC is disabled for all traffic that is processed by any filters that specify the callout for the filter's action. I developed the WFP driver for windows-7 4 years back, i.e. this flag is not in my driver, I get big packet size in my driver at RX path. Disabling RSC using Disable-NetAdapterRsc -Name * command works.

    Does anyone have an idea, is this issue in OS (Windows 10 1703)?

    Thanks in advance
