10.8.2.4.2.2 Set Firmware Proxying Configuration
This command is used to provide information to Firmware on how to implement protocol offloads
supported by the I210.
The Firmware Proxying Configuration command includes a series of two values
{Command type and version, Command Data for this type of command}
Currently only one Configuration command is defined:
1. No Match - Command defines expected behavior when receiving a Proxying packet that’s not
supported.
Note: the I210 keeps its proxy settings after D3 to D0 transition, until they are disabled by host.
However, the proxy filters are reset by PERST assertion/deassertion that occurs when
transiting from D3 to D0 via Dr state. Therefore, FW is required to reconfigure the proxy
filters after PERST deassertion, in the aim to maintain proxying until the driver is up again. To
avoid a race condition between FW and SW while accessing proxy registers, the driver should
first disable proxying via the host interface before modifying the proxy registers.
If the structure is too big to transfer in one time the driver can ask for additional pages by incrementing
the page field.
