[PATCH] ieee80211: small ERP handling additions
This adds a flag to the ieee80211_network structure which indicates whether
the stored erp_value is valid (a check against 0 is not enough, since an ERP
of 0 is valid and very meaningful).
I also added the ERP IE bit-definitions to ieee80211.h.
This is needed by some upcoming softmac patches.
