2019-09-13ip: support SO_MARK cmsgWillem de Bruijn
Enable setting skb->mark for UDP and RAW sockets using cmsg. This is analogous to existing support for TOS, TTL, txtime, etc. Packet sockets already support this as of commit c7d39e32632e ("packet: support per-packet fwmark for af_packet sendmsg"). Similar to other fields, implement by 1. initialize the sockcm_cookie.mark from socket option sk_mark 2. optionally overwrite this in ip_cmsg_send/ip6_datagram_send_ctl 3. initialize inet_cork.mark from sockcm_cookie.mark 4. initialize each (usually just one) skb->mark from inet_cork.mark Step 1 is handled in one location for most protocols by ipcm_init_sk as of commit 351782067b6b ("ipv4: ipcm_cookie initializers").

Report chains and chain_signal in ieee80211_rx_status. It is useful for program such as tcpdump to see if the antennas are well connected/placed. 8822C is able to receive CCK rates with 2 antennas, while 8822B can only use 1 antenna path to receive CCK rates.

2019-09-13rtw88: add dynamic cck pd mechanismTzu-En Huang
This mechanism reduces the numbers of false alram in cck rate by dynamically adjusting the value of power threshold and cs_ratio. We determine the new value by three factors, which are rssi, false alarm count and igi. Based on these factors, we define the current condition into five levels. Compared to the previous level, if the level is changed, we set the new values for power threshold and cs_ratio.

2019-09-13rtw88: 8822c: add SW DPK supportTzu-En Huang
Power amplifiers are not linear components, and require DPK to reduce its nonlinearity. DPK is called Digital Pre-distortion Calibration, can be used to compensate the output of power. DPK tracking is in charge of tracking the thermal changes. And it then shifts the power curve accordingly, which makes the power output remains linear even if the PA works in different temperature. To perform DPK, the parameter table should also be updated. And the table will be applied when device is powered on. Then DPK will reference the values to calibrate.

2019-09-13rtw88: 8822c: add FW IQK supportYan-Hsuan Chuang
Add support for doing IQK in firmware Ideally the RF component's I/Q vectors should be orthogonal, but usually they are not. So we need to calibrate for the RF components, ex. PA/LNA, ADC/DAC. And if the I/Q vectors are more orthogonal, the mixed signal will have less deviation. This helps with those rates with higher modulation (MCS8-9), because they have more strict EVM/SNR requirement. Also the better of the quality of the signal, the longer it can propagate, and the better throughput performance we can get.

OPAL loads kernel & initrd at 512MB offset (256MB size), also exported as ibm,opal/dump/fw-load-area. So, if boot memory size of FADump is less than 768MB, kernel memory to be exported as '/proc/vmcore' would be overwritten by f/w while loading kernel & initrd. To avoid such a scenario, enforce a minimum boot memory size of 768MB on OPAL platform and skip using FADump if a newer F/W version loads kernel & initrd above 768MB. Also, irrespective of RMA size, set the minimum boot memory size expected on pseries platform at 320MB. This is to avoid inflating the minimum memory requirements on systems with 512M/1024M RMA size.
