2024-02-08wifi: mac80211: introduce 'channel request'Johannes Berg
For channel contexts, mac80211 currently uses the cfg80211 chandef struct (control channel, center freq(s), width) to define towards drivers and internally how these behave. In fact, there are _two_ such structs used, where the min_def can reduce bandwidth according to the stations connected. Unfortunately, with EHT this is longer be sufficient, at least not for all hardware. EHT requires that non-AP STAs that are connected to an AP with a lower bandwidth than it (the AP) advertises (e.g. 160 MHz STA connected to 320 MHz AP) still be able to receive downlink OFDMA and respond to trigger frames for uplink OFDMA that specify the position and bandwidth for the non-AP STA relative to the channel the AP is using. Therefore, they need to be aware of this, and at least for some hardware (e.g. Intel) this awareness is in the hardware. As a result, use of the "same" channel may need to be split over two channel contexts where they differ by the AP being used. As a first step, introduce a concept of a channel request ('chanreq') for each interface, to control the context it requests. This step does nothing but reorganise the code, so that later the AP's chandef can be added to the request in order to handle the EHT case described above.

2024-02-08wifi: mac80211: simplify non-chanctx driversJohannes Berg
There are still surprisingly many non-chanctx drivers, but in mac80211 that code is a bit awkward. Simplify this by having those drivers assign 'emulated' ops, so that the mac80211 code can be more unified between non-chanctx/chanctx drivers. This cuts the number of places caring about it by about 15, which are scattered across - now they're fewer and no longer in the channel context handling.

mac80211 is fully switching over to the internal TX queue (iTXQ) implementation. Update all drivers not yet providing the now mandatory wake_tx_queue() callback.

We'll use bss_conf for per-link configuration later, so move out all the non-link-specific data out into a new struct ieee80211_vif_cfg used in the vif. Some adjustments were done with the following spatch: @@ expression sdata; struct ieee80211_vif *vifp; identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator }; @@ ( -sdata->vif.bss_conf.var +sdata->vif.cfg.var | -vifp->bss_conf.var +vifp->cfg.var ) @bss_conf@ struct ieee80211_bss_conf *bss_conf; identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator }; @@ -bss_conf->var +vif_cfg->var (though more manual fixups were needed, e.g. replacing "vif_cfg->" by "vif->cfg." in many files.)

2020-03-17staging: vt6656: Use BIT_ULL() macro instead of bit shift operationOscar Carter
Replace the bit left shift operation with the BIT_ULL() macro and remove the unnecessary mask off operation against the bit_nr variable. This mask is only there for legacy reasons. Originally it was 31 (0x1f) and the bit_nr variable spread across an mc_filter array with two u32 elements. Now, this mask is not needed because its value is 0x3f and the mc_filter variable is an u64 type. In this situation, the 26 bit right shift operation against the value returned by the ether_crc function set the bit_nr variable to the following value: bit 31 to bit 6 -> All 0 (due to the bit shift operation happens over an unsigned type). bit 5 to bit 0 -> The 6 msb bits of the value returned by the ether_crc function. The purpose of the 0x3f mask against the bit_nr variable is to reset (set to 0) the 26 msb bits (bit 31 to bit 6), but these bits are yet 0. So, the mask off operation is now unnecessary.

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the vt6656 driver files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2017-04-28drivers:staging:vt6656: remove usb_device_reset in main_usb.c:Chewie Lin
Removed the usb_device_reset(), replace with call to usb_reset_device() directly. Plus it removes the confusing function name and addressed the checkpatch warning. This change also swaps string in the dev_warn() call with __func__ argument to "vt6656_probe" instead of literal string "usb_reset_device". WARNING: Prefer using "%s", __func__ to embedded function names #417: FILE: main_usb.c:417: + "usb_device_reset fail status=%d\n", status); total: 0 errors, 1 warnings, 1058 lines checked And after fix: main_usb.c has no obvious style problems and is ready for submission.
