Subject: [PATCH 3/3] net: airoha: Add the capability to allocate hfwd
|
|
descriptors in SRAM
|
|
|
|
In order to improve packet processing and packet forwarding
|
|
performances, EN7581 SoC supports consuming SRAM instead of DRAM for
|
|
hw forwarding descriptors queue.
|
|
For downlink hw accelerated traffic request to consume SRAM memory
|
|
for hw forwarding descriptors queue.
