rtw88: replace tx tasklet with work queue

2021-02-12T07:51:09+00:00

Replace tasklet so we can do tx scheduling in parallel. Since throughput
is delay-sensitive in most cases, we allocate a dedicated, high priority
wq for our needs.

rtw88: add napi support

2021-02-12T07:50:58+00:00

Use napi to reduce overhead on rx interrupts.

Driver used to interrupt kernel for every Rx packet, this could
affect both system and network performance. NAPI is a mechanism that
uses polling when processing huge amount of traffic, by doing this
the number of interrupts can be decreased.

Network performance can also benefit from this patch. Since TCP
connection is bidirectional and acks are required for every several
packets. These ack packets occupie the PCI bus bandwidth and could
lead to performance degradation.

When napi is used, GRO receive is enabled by default in the mac80211
stack. So mac80211 won't pass every RX TCP packets to the kernel TCP
network stack immediately. Instead an aggregated large length TCP packet
will be delivered.

This reduces the tx acks sent and gains rx performance. After the patch,
the Rx throughput increases about 25Mbps in 11ac.

rtw88: add rts condition

2021-02-12T07:50:55+00:00

Since we set the IEEE80211_HW_HAS_RATE_CONTROL flag, so use_rts in
ieee80211_tx_info will never be set in the ieee80211_xmit_fast path.
Add length check for skb to decide whether rts is needed.

rtw88: add dynamic rrsr configuration

2021-02-12T07:50:53+00:00

Register rrsr determines the response rate we send.
In field tests, using rate higher than current tx rate could lead
to difficulty for the receiving end to receive management/control
frames. Calculate current modulation level by tx rate then cross out
rate higher than those.
