From 0edd5b44913cd0aba6f23b626b407f70bb3fb018 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Wed, 7 Sep 2005 00:48:31 -0400 Subject: [wireless ieee80211,ipw2200] Lindent source code No code changes, just Lindent + manual fixups. This prepares us for updating to the latest Intel driver code, plus gives the source code a nice facelift. --- net/ieee80211/ieee80211_tx.c | 66 +++++++++++++++++++------------------------- 1 file changed, 28 insertions(+), 38 deletions(-) (limited to 'net/ieee80211/ieee80211_tx.c') diff --git a/net/ieee80211/ieee80211_tx.c b/net/ieee80211/ieee80211_tx.c index b7ea3e25e25..c9aaff3fea1 100644 --- a/net/ieee80211/ieee80211_tx.c +++ b/net/ieee80211/ieee80211_tx.c @@ -45,10 +45,8 @@ #include - /* - 802.11 Data Frame ,-------------------------------------------------------------------. @@ -82,7 +80,6 @@ Desc. | IV | Encrypted | ICV | `-----------------------' Total: 8 non-data bytes - 802.3 Ethernet Data Frame ,-----------------------------------------. @@ -131,7 +128,7 @@ payload of each frame is reduced to 492 bytes. static u8 P802_1H_OUI[P80211_OUI_LEN] = { 0x00, 0x00, 0xf8 };
