Subject: [PATCH 0/4] cfg80211: few country IE parse fixes

John, this series has a few country IE fixes some of which
Benoit reported. The fix I made goes in with an enhancement
which reduces the number of rules created if the AP is stupid
and sends congigious channels, never making use of the number
of channels in the triplets.

I've tested this against an AP issuing these country IE
triplets below:

[1]
[2]
[36]
[40]

[1]
[2-4]
[5-12]
[36]
[40-44]

[1-4]
[5-7]
[36-44]
[48-64]

[36-36]
[40-40]
[44-44]
[48-48]
[52-52]
[56-56]
[60-60]
[64-64]
[100-100]
[104-104]
[108-108]
[112-112]
[116-116]
[120-120]
[124-124]
[128-128]
[132-132]
[136-136]
[140-140]

All these country IEs now only produce two triplets on regulatory rules.

I generated these with hostapd using a debug patch for country IEs:

Luis R. Rodriguez (4):
  cfg80211: add debug print when we drop a bogus country IE
  cfg80211: fix 2 GHz subband calculation for country IEs
  cfg80211: process the max power on a country IE
  cfg80211: Fix country IE parsing for single channel triplets
