The size of the status_driver_data field was not adjusted when the is_valid_ack_signal field was added. Since the size of struct ieee80211_tx_info is limited, replace the is_valid_ack_signal field with a flags field, and adjust the struct size accordingly. Signed-off-by:

There's currently only one driver that reports CHECKSUM_COMPLETE, that is iwlwifi. The current hardware there calculates checksum after the SNAP header, but only RFC 1042 (and some other cases, but replicating the exact hardware logic for corner cases in the driver seemed awkward.) Newer generations of hardware will checksum _including_ the SNAP, which makes things easier. To handle that, simply always assume the checksum _includes_ the SNAP header, which this patch does, requiring to first add it for older iwlwifi hardware, and then remove it again later on conversion. Alternatively, we could have: 1) Always assumed the checksum starts _after_ the SNAP header; the problem with this is that we'd have to replace the exact "what is the SNAP" check in iwlwifi that cfg80211 has. 2) Made it configurable with some flag, but that seemed like too much complexity.

In UHB connection we don't have any HT/VHT elemens so in order to calculate the max RX-NSS we need also to look at HE capa element, this causes to limit us to max rx nss in UHB to 1. Also anyway we need to look at HE max rx NSS and not only at HT/VHT capa to determine the max rx nss over the connection. Signed-off-by:

The driver was enabling IRQs before the message processing was initialized. This could cause IRQs to come in too early and crash the driver. Instead, move the IRQ enable and hostready to a bus preinit function, at which point everything is properly initialized. Fixes: 9e37f045 ("brcmfmac: Adding PCIe bus layer support.") Reviewed-by:

The alignment check was wrong (e.g. & 4 instead of & 3), and the logic was also inefficient if the length was not a multiple of 4, since it would needlessly fall back to copying the entire buffer bytewise. We already have a perfectly good memcpy_toio function, so just call that instead of rolling our own copy logic here. brcmf_pcie_init_ringbuffers was already using it anyway.

This is a second attempt at honering the country code send out by access points. This was first added in commit b0b524f0 ("brcmfmac: use ISO3166 country code and 0 rev as fallback"). Subsequently this was reverted in commit 151a7c12 ("Revert "brcmfmac: use ISO3166 country code and 0 rev as fallback""), because it was causing issues with AP mode on some brcmfmac models (specifically on BCM4359/9). Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are all special world-wide compatibility ccode-s. Most of these world-wide ccode-s allow passive scan mode only for 2.4GHz channels 12-14, only enabling them when an AP is seen on them. But at least on brcmfmac43455 devices this is not working correctly, these do not see accesspoints on channels 12-14 unless the ccode is changes to a country where these channels are allowed. Translating received country codes to an ISO3166 country code and 0 rev ccreq fixes devices using a brcmfmac43455 with a X2/XT/XU/XV/ALL ccode not seeing accesspoints on channels 12-14. To avoid this causing issues on other brcmfmac models again, the fallback is limited to only brcmfmac4345* chips this time.
