PCI_FIND_NEXT_HT_CAP(9) 					Hardware Interfaces					   PCI_FIND_NEXT_HT_CAP(9)

NAME
pci_find_next_ht_capability - query a device's Hypertransport capabilities SYNOPSIS
int pci_find_next_ht_capability(struct pci_dev * dev, int pos, int ht_cap); ARGUMENTS
dev PCI device to query pos Position from which to continue searching ht_cap Hypertransport capability code DESCRIPTION
To be used in conjunction with pci_find_ht_capability to search for all capabilities matching ht_cap. pos should always be a value returned from pci_find_ht_capability. NB. To be 100% safe against broken PCI devices, the caller should take steps to avoid an infinite loop. COPYRIGHT

STRUCT 
IEEE80211_STA(9) Advanced driver interface STRUCT IEEE80211_STA(9) NAME
struct_ieee80211_sta - station table entry SYNOPSIS
struct ieee80211_sta { u32 supp_rates[IEEE80211_NUM_BANDS]; u8 addr[ETH_ALEN]; u16 aid; struct ieee80211_sta_ht_cap ht_cap; struct ieee80211_sta_vht_cap vht_cap; bool wme; u8 uapsd_queues; u8 max_sp; u8 rx_nss; enum ieee80211_sta_rx_bandwidth bandwidth; enum ieee80211_smps_mode smps_mode; u8 drv_priv[0]; }; MEMBERS
supp_rates[IEEE80211_NUM_BANDS] Bitmap of supported rates (per band) addr[ETH_ALEN] MAC address aid AID we assigned to the station if we're an AP ht_cap HT capabilities of this STA; restricted to our own capabilities vht_cap VHT capabilities of this STA; restricted to our own capabilities wme indicates whether the STA supports WME. Only valid during AP-mode. uapsd_queues bitmap of queues configured for uapsd. Only valid if wme is supported. max_sp max Service Period. Only valid if wme is supported. rx_nss in HT/VHT, the maximum number of spatial streams the station can receive at the moment, changed by operating mode notifications and capabilities. The value is only valid after the station moves to associated state. bandwidth current bandwidth the station can receive with smps_mode current SMPS mode (off, static or dynamic) drv_priv[0] data area for driver use, will always be aligned to sizeof(void *), size is determined in hw information. DESCRIPTION
A station table entry represents a station we are possibly communicating with. Since stations are RCU-managed in mac80211, any ieee80211_sta pointer you get access to must either be protected by rcu_read_lock explicitly or implicitly, or you must take good care to not use such a pointer after a call to your sta_remove callback that removed it.
