From bf45abeb1d917e92775b4523ba0ddcfd331464b4 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Thu, 18 Oct 2007 17:16:20 -0700 Subject: [PATCH] NAPI: kconfig prompt and deleted doc file - make the kconfig NAPI option prompt consistent across all net drivers (other than EXPERIMENTAL; can it now be removed also, or is the new napi_struct implementation now EXPERIMENTAL ?) - remove comment about the now-deleted NAPI_HOWTO.txt file - clean up typos in Tulip NAPI & Interrupt Mitigation Signed-off-by: Randy Dunlap Signed-off-by: Jeff Garzik --- drivers/net/Kconfig | 37 +++++-------------------------------- drivers/net/tulip/Kconfig | 14 ++++++-------- 2 files changed, 11 insertions(+), 40 deletions(-) diff --git a/drivers/net/Kconfig b/drivers/net/Kconfig index 83d52c8acab..1a92dc6f927 100644 --- a/drivers/net/Kconfig +++ b/drivers/net/Kconfig @@ -1293,9 +1293,6 @@ config PCNET32_NAPI deployed on potentially unfriendly networks (e.g. in a firewall), then say Y here. - See for more - information. - If in doubt, say N. config AMD8111_ETH @@ -1313,7 +1310,7 @@ config AMD8111_ETH will be called amd8111e. config AMD8111E_NAPI - bool "Enable NAPI support" + bool "Use RX polling (NAPI)" depends on AMD8111_ETH help NAPI is a new driver API designed to reduce CPU and interrupt load @@ -1324,9 +1321,6 @@ config AMD8111E_NAPI deployed on potentially unfriendly networks (e.g. in a firewall), then say Y here. - See for more - information. - If in doubt, say N. config ADAPTEC_STARFIRE @@ -1355,9 +1349,6 @@ config ADAPTEC_STARFIRE_NAPI deployed on potentially unfriendly networks (e.g. in a firewall), then say Y here. - See for more - information. - If in doubt, say N. config AC3200 @@ -1431,7 +1422,7 @@ config FORCEDETH called forcedeth. config FORCEDETH_NAPI - bool "Use Rx and Tx Polling (NAPI) (EXPERIMENTAL)" + bool "Use Rx Polling (NAPI) (EXPERIMENTAL)" depends on FORCEDETH && EXPERIMENTAL help NAPI is a new driver API designed to reduce CPU and interrupt load @@ -1442,9 +1433,6 @@ config FORCEDETH_NAPI deployed on potentially unfriendly networks (e.g. in a firewall), then say Y here. - See for more - information. - If in doubt, say N. config CS89x0 @@ -1756,9 +1744,6 @@ config VIA_RHINE_NAPI deployed on potentially unfriendly networks (e.g. in a firewall), then say Y here. - See for more - information. - config LAN_SAA9730 bool "Philips SAA9730 Ethernet support" depends on NET_PCI && PCI && MIPS_ATLAS @@ -2003,9 +1988,6 @@ config E1000_NAPI deployed on potentially unfriendly networks (e.g. in a firewall), then say Y here. - See for more - information. - If in doubt, say N. config E1000_DISABLE_PACKET_SPLIT @@ -2099,7 +2081,7 @@ config R8169 will be called r8169.
