avatar 21345d1652 Fixing WEP bustage in hostap mode since 5.2-RELEASE. 
- WEP TX fix:

  The original code called software crypto, ieee80211_crypto_encap(),
which never worked since IEEE80211_KEY_SWCRYPT was never flagged due to
ieee80211_crypto_newkey() assumes that wi always supports hardware based
crypto regardless of operational mode(by virtue of IEEE80211_C_WEP).
This fix works around that issue by adding wi_key_alloc() to force
the use of s/w crypto.  Also if anyone ever decides to cleanup ioctl
handling where key changes wouldn't cause a call to wi_init() every time,
we'll need wi_key_alloc() to DTRT.

  In addition to that, this fix also adds code to wi_write_wep() to force
existing keys to be switched between h/w and s/w crypto such that an
operation mode change(sta <-> hostap) will flag IEEE80211_KEY_SWCRYPT
properly.

- WEP RX fix:

  Clear IEEE80211_F_DROPUNENC even in hostap mode.  Quote from Sam:

	"This is really gross but I don't see an easy way around it.
	By doing it we lose the ability to independently drop unencode
	frames (and support mixed wep/!wep use).  We should really be
	setting the EXCLUDE_UNENCRYPTED flag written in wi_write_wep
	based on IEEE80211_F_DROPUNENC but with our clearing it we can't
	depend on it being set properly."
