brcmfmac: use wiphy_read_of_freq_limits to respect limits from DT
This new helper reads extra frequency limits specified in DT and disables unavailable chanels. This is useful for devices (like home routers) with chipsets limited e.g. by board design. In order to respect info read from DT we simply need to check for IEEE80211_CHAN_DISABLED bit when constructing channel info.

E ] to confirm neighbour: - UDP IPv4/IPv6 - ICMPv4 PING - RAW IPv4/IPv6 - L2TP/IPv6 MSG_CONFIRM for other purposes (fix not needed): - CAN Sending without locking the socket: - UDP (when no cork) - RAW (when hdrincl=1) Redirects from old to new GW: - rt6_do_redirect The patchset includes the following changes: 1. sock: add sk_dst_pending_confirm flag - used only by TCP with patch 4 to remember the received indication in sk->sk_dst_pending_confirm 2. net: add dst_pending_confirm flag to skbuff - skb->dst_pending_confirm will be used by all protocols in following patches, via skb_{set,get}_dst_pending_confirm 3. sctp: add dst_pending_confirm flag - SCTP uses per-transport dsts and can not use sk->sk_dst_pending_confirm like TCP 4. tcp: replace dst_confirm with sk_dst_confirm 5. net: add confirm_neigh method to dst_ops - IPv4 and IPv6 provision for slow neigh lookups for MSG_PROBE users. I decided to use neigh lookup only for this case because on MSG_PROBE the skb may pass MTU checks but it does not reach the neigh confirmation code. This patch will be used from patch 6. - xfrm_confirm_neigh: we use the last tunnel address, if present. When there are only transports, the original dest address is used. 6. net: use dst_confirm_neigh for UDP, RAW, ICMP, L2TP - dst_confirm conversion for UDP, RAW, ICMP and L2TP/IPv6 - these protocols use MSG_CONFIRM propagated by ip*_append_data to skb->dst_pending_confirm. sk->sk_dst_pending_confirm is not used because some sending paths do not lock the socket. For MSG_PROBE we use the slow lookup (dst_confirm_neigh). - there are also 2 cases that need the slow lookup: __ip6_rt_update_pmtu and rt6_do_redirect. I hope &ipv6_hdr(skb)->saddr is the correct nexthop address to use here. 7. net: pending_confirm is not used anymore - I failed to understand the CXGB* code, I see dst_confirm() calls but I'm not sure dst_neigh_output() was called. For now I just removed the dst->pending_confirm flag and left all dst_confirm() calls there. Any better idea? - Now may be old function neigh_output() should be restored instead of dst_neigh_output? ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
