---help---
Say Y here if you have a Realtek 8169 PCI Gigabit Ethernet adapter.
To compile this driver as a module, choose M here: the module
will be called r8169. This is recommended.
-
-config R8169_NAPI
- bool "Use Rx and Tx Polling (NAPI) (EXPERIMENTAL)"
- depends on R8169 && EXPERIMENTAL
- help
- NAPI is a new driver API designed to reduce CPU and interrupt load
- when the driver is receiving lots of packets from the card. It is
- still somewhat experimental and thus not yet enabled by default.
-
- If your estimated Rx load is 10kpps or more, or if the card will be
- deployed on potentially unfriendly networks (e.g. in a firewall),
- then say Y here.
-
- See <file:Documentation/networking/NAPI_HOWTO.txt> for more
- information.
-
- If in doubt, say N.

/*
-=========================================================================
- r8169.c: A RealTek RTL-8169 Gigabit Ethernet driver for Linux kernel 2.4.x.
- --------------------------------------------------------------------
-
- History:
- Feb 4 2002 - created initially by ShuChen <shuchen@xxxxxxxxxxxxxx>.
- May 20 2002 - Add link status force-mode and TBI mode support.
- 2004 - Massive updates. See kernel SCM system for details.
-=========================================================================
- 1. [DEPRECATED: use ethtool instead] The media can be forced in 5 modes.
- Command: 'insmod r8169 media = SET_MEDIA'
- Ex: 'insmod r8169 media = 0x04' will force PHY to operate in
100Mpbs Half-duplex.
-
- SET_MEDIA can be:
- _10_Half = 0x01
- _10_Full = 0x02
- _100_Half = 0x04
- _100_Full = 0x08
- _1000_Full = 0x10
-
- 2. Support TBI mode.
-=========================================================================
-VERSION 1.1 <2002/10/4>
-
- The bit4:0 of MII register 4 is called "selector field", and have to be
- 00001b to indicate support of IEEE std 802.3 during NWay process of
- exchanging Link Code Word (FLP).
-
-VERSION 1.2 <2002/11/30>
-
- - Large style cleanup
- - Use ether_crc in stock kernel (linux/crc32.h)
- - Copy mc_filter setup code from 8139cp
- (includes an optimization, and avoids set_bit use)
-
-VERSION 1.6LK <2004/04/14>
-
- - Merge of Realtek's version 1.6
- - Conversion to DMA API
- - Suspend/resume
- - Endianness
- - Misc Rx/Tx bugs
-
-VERSION 2.2LK <2005/01/25>
-
- - RX csum, TX csum/SG, TSO
- - VLAN
- - baby (< 7200) Jumbo frames support
- - Merge of Realtek's version 2.2 (new phy)
