staging: vt6656: Remove memory buffer from vnt_download_firmware.

2020-01-22T08:52:39+00:00

The memory buffer is being done twice here as vnt_control_out passes it straight to kmemdup. Remove buffer and add const to the variable in vnt_control_out to pass the pointer to it.

staging: vt6656: Just check NEWRSR_DECRYPTOK for RX_FLAG_DECRYPTED.

2020-01-22T08:52:38+00:00

At present the driver does a number of checks for RX_FLAG_DECRYPTED. Remove all these and just pass check NEWRSR_DECRYPTOK mac80211 will handle the processing of the sk_buff and dispose of it. This means that mac80211 can do unsupported encryption modes on stack.

staging: vt6656: Use vnt_rx_tail struct for tail variables.

2020-01-22T08:52:38+00:00

Place tsf_time, sq, new_rsr, rssi, rsr and sq3 packed in the structure. Unused variables are removed along with skb_data and structure is placed beyond vnt_rx_header + pay_load_with_padding on skb->data.

staging: vt6656: create vnt rx header for sk_buff.

2020-01-22T08:52:38+00:00

vnt_rx_header contains the structure of the original variables wbk_status, rx_sts, rx_rate and pay_load_len packed. Replace all the old variables for the ones in this.

staging: vt6656: Simplify RX finding bit rates

2020-01-22T08:52:38+00:00

The bit rate can be found by multiplying the rate value by 5. Use rx_bitrate to compared to sband bitrates removing the need to find it by hw_value. Signed-off-by: Malcolm Priestley Link: https://lore.kernel.org/r/50d3c4b8-6d17-4fae-ce9c-88a50614450f@gmail.com Signed-off-by: Greg Kroah-Hartman

Merge 5.5-rc6 into staging-next

2020-01-13T06:52:17+00:00

We need the staging fixes in here as well. Signed-off-by: Greg Kroah-Hartman

staging: vt6656: Move ieee80211_rx_status off stack.

2020-01-10T12:49:20+00:00

ieee80211_rx_status off stack to IEEE80211_SKB_RXCB (skb->cb) removing the need to copy on to it. skb->cb is always present as a clean buffer so simply fill it in.

staging: vt6656: Fix false Tx excessive retries reporting.

2020-01-10T12:49:19+00:00

The driver reporting IEEE80211_TX_STAT_ACK is not being handled correctly. The driver should only report on TSR_TMO flag is not set indicating no transmission errors and when not IEEE80211_TX_CTL_NO_ACK is being requested.

staging: vt6656: use NULLFUCTION stack on mac80211

2020-01-10T12:49:19+00:00

It appears that the drivers does not go into power save correctly the NULL data packets are not being transmitted because it not enabled in mac80211. The driver needs to capture ieee80211_is_nullfunc headers and copy the duration_id to it's own duration data header.

staging: vt6656: correct packet types for CTS protect, mode.

2020-01-10T12:49:19+00:00

It appears that the driver still transmits in CTS protect mode even though it is not enabled in mac80211. That is both packet types PK_TYPE_11GA and PK_TYPE_11GB both use CTS protect. The only difference between them GA does not use B rates. Find if only B rate in GB or GA in protect mode otherwise transmit packets as PK_TYPE_11A.
