From: Wright Feng <wright.feng@xxxxxxxxxxx> To create virtual station interface for RSDB and VSDB, we add interface creation version 1, 2 and 3 supports The structures of each version are different and only version 3 and later version are able to get interface creating version from firmware side. The patch has been verified two concurrent stations pings test with interface create version 1: 89342(4359b1)-PCIE: 9.40.100 interface create version 2: 4373a0-sdio: 13.10.271 interface create version 3: 4373a0-sdio: 13.35.48 Signed-off-by: Wright Feng <wright.feng@xxxxxxxxxxx> Signed-off-by: Chi-hsien Lin <chi-hsien.lin@xxxxxxxxxxxx> Signed-off-by: Ian Lin <ian.lin@xxxxxxxxxxxx> --- .../broadcom/brcm80211/brcmfmac/cfg80211.c | 148 +++++++++++++++--- 1 file changed, 124 insertions(+), 24 deletions(-) diff --git a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c index e352bc6e015c..2082e255f031 100644 --- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c +++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c @@ -234,17 +234,46 @@ struct parsed_vndr_ies { struct parsed_vndr_ie_info ie_info[VNDR_IE_PARSE_LIMIT]; }; +#define WL_INTERFACE_CREATE_VER_1 1 +#define WL_INTERFACE_CREATE_VER_2 2 +#define WL_INTERFACE_CREATE_VER_3 3 +#define WL_INTERFACE_CREATE_VER_MAX WL_INTERFACE_CREATE_VER_3 + #define WL_INTERFACE_MAC_DONT_USE 0x0 #define WL_INTERFACE_MAC_USE 0x2 #define WL_INTERFACE_CREATE_STA 0x0 #define WL_INTERFACE_CREATE_AP 0x1 -struct wl_interface_create { - u16 ver; - u32 flags; - u8 mac_addr[ETH_ALEN]; - u8 pad[13]; +struct wl_interface_create_v1 { + u16 ver; /* structure version */ + u32 flags; /* flags for operation */ + u8 mac_addr[ETH_ALEN]; /* MAC address */ + u32 wlc_index; /* optional for wlc index */ +}; + +struct wl_interface_create_v2 { + u16 ver; /* structure version */ + u8 pad1[2]; + u32 flags; /* flags for operation */ + u8 mac_addr[ETH_ALEN]; /* MAC address */ + u8 iftype; /* type of interface created */ + u8 pad2; + u32 wlc_index; /* optional for wlc index */ +}; + +struct wl_interface_create_v3 { + u16 ver; /* structure version */ + u16 len; /* length of structure + data */ + u16 fixed_len; /* length of structure */ + u8 iftype; /* type of interface created */ + u8 wlc_index; /* optional for wlc index */ + u32 flags; /* flags for operation */ + u8 mac_addr[ETH_ALEN]; /* MAC address */ + u8 bssid[ETH_ALEN]; /* optional for BSSID */ + u8 if_index; /* interface index request */ + u8 pad[3]; + u8 data[]; /* Optional for specific data */ }; static u8 nl80211_band_to_fwil(enum nl80211_band band) @@ -534,16 +563,14 @@ static int brcmf_get_first_free_bsscfgidx(struct brcmf_pub *drvr) return -ENOMEM; } -static void brcmf_set_sta_iface_macaddr(struct brcmf_if *ifp, - struct wl_interface_create *iface) +static void brcmf_set_vif_sta_macaddr(struct brcmf_if *ifp, u8 *mac_addr) { u8 mac_idx = ifp->drvr->sta_mac_idx; /* set difference MAC address with locally administered bit */ - iface->flags |= WL_INTERFACE_MAC_USE; - memcpy(iface->mac_addr, ifp->mac_addr, ETH_ALEN); - iface->mac_addr[0] |= 0x02; - iface->mac_addr[3] ^= mac_idx ?
