 *	e100.c: Intel(R) PRO/100 ethernet driver

    71

 *

    72

 *	(Re)written 2003 by scott.feldman@intel.com.  Based loosely on

    73

 *	original e100 driver, but better described as a munging of

    74

 *	e100, e1000, eepro100, tg3, 8139cp, and other drivers.

    75

 *

    76

 *	References:

    77

 *		Intel 8255x 10/100 Mbps Ethernet Controller Family,

    78

 *		Open Source Software Developers Manual,

    79

    80

 *

    81

 *

    82

 *	                      Theory of Operation

    83

 *

    84

 *	I.   General

    85

 *

    86

 *	The driver supports Intel(R) 10/100 Mbps PCI Fast Ethernet

    87

 *	controller family, which includes the 82557, 82558, 82559, 82550,

    88

 *	82551, and 82562 devices.  82558 and greater controllers

    89

 *	integrate the Intel 82555 PHY.  The controllers are used in

    90

 *	server and client network interface cards, as well as in

    91

 *	LAN-On-Motherboard (LOM), CardBus, MiniPCI, and ICHx

    92

 *	configurations.  8255x supports a 32-bit linear addressing

    93

 *	mode and operates at 33Mhz PCI clock rate.

    94

 *

    95

 *	II.  Driver Operation

    96

 *

    97

 *	Memory-mapped mode is used exclusively to access the device's

    98

 *	shared-memory structure, the Control/Status Registers (CSR). All

    99

 *	setup, configuration, and control of the device, including queuing

   100

 *	of Tx, Rx, and configuration commands is through the CSR.

   101

 *	cmd_lock serializes accesses to the CSR command register.  cb_lock

   102

 *	protects the shared Command Block List (CBL).

   103

 *

   104

 *	8255x is highly MII-compliant and all access to the PHY go

   105

 *	through the Management Data Interface (MDI).  Consequently, the

   106

 *	driver leverages the mii.c library shared with other MII-compliant

   107

 *	devices.

   108

 *

   109

 *	Big- and Little-Endian byte order as well as 32- and 64-bit

   110

 *	archs are supported.  Weak-ordered memory and non-cache-coherent

   111

 *	archs are supported.

   112

 *

   113

 *	III. Transmit

   114

 *

   115

 *	A Tx skb is mapped and hangs off of a TCB.  TCBs are linked

   116

 *	together in a fixed-size ring (CBL) thus forming the flexible mode

   117

 *	memory structure.  A TCB marked with the suspend-bit indicates

   118

 *	the end of the ring.  The last TCB processed suspends the

   119

 *	controller, and the controller can be restarted by issue a CU

   120

 *	resume command to continue from the suspend point, or a CU start

   121

 *	command to start at a given position in the ring.

   122

 *

   123

 *	Non-Tx commands (config, multicast setup, etc) are linked

   124

 *	into the CBL ring along with Tx commands.  The common structure

   125

 *	used for both Tx and non-Tx commands is the Command Block (CB).

   126

 *

   127

 *	cb_to_use is the next CB to use for queuing a command; cb_to_clean

   128

 *	is the next CB to check for completion; cb_to_send is the first

   129

 *	CB to start on in case of a previous failure to resume.  CB clean

   130

 *	up happens in interrupt context in response to a CU interrupt.

   131

 *	cbs_avail keeps track of number of free CB resources available.

   132

 *

   133

 * 	Hardware padding of short packets to minimum packet size is

   134

 * 	enabled.  82557 pads with 7Eh, while the later controllers pad

   135

 * 	with 00h.

   136

 *

   137

 *	IV.  Receive

   138

 *

   139

 *	The Receive Frame Area (RFA) comprises a ring of Receive Frame

   140

 *	Descriptors (RFD) + data buffer, thus forming the simplified mode

   141

 *	memory structure.  Rx skbs are allocated to contain both the RFD

   142

 *	and the data buffer, but the RFD is pulled off before the skb is

   143

 *	indicated.  The data buffer is aligned such that encapsulated

   144

 *	protocol headers are u32-aligned.  Since the RFD is part of the

   145

 *	mapped shared memory, and completion status is contained within

   146

 *	the RFD, the RFD must be dma_sync'ed to maintain a consistent

   147

 *	view from software and hardware.

   148

 *

   149

 *	In order to keep updates to the RFD link field from colliding with

   150

 *	hardware writes to mark packets complete, we use the feature that

   151

 *	hardware will not write to a size 0 descriptor and mark the previous

   152

 *	packet as end-of-list (EL).   After updating the link, we remove EL

   153

 *	and only then restore the size such that hardware may use the

   154

 *	previous-to-end RFD.

   155

 *

   156

 *	Under typical operation, the  receive unit (RU) is start once,

   157

 *	and the controller happily fills RFDs as frames arrive.  If

   158

 *	replacement RFDs cannot be allocated, or the RU goes non-active,

   159

 *	the RU must be restarted.  Frame arrival generates an interrupt,

   160

 *	and Rx indication and re-allocation happen in the same context,

   161

 *	therefore no locking is required.  A software-generated interrupt

   162

 *	is generated from the watchdog to recover from a failed allocation

   163

 *	scenario where all Rx resources have been indicated and none re-

   164

 *	placed.

   165

 *

   166

 *	V.   Miscellaneous

   167

 *

   168

 * 	VLAN offloading of tagging, stripping and filtering is not

   169

 * 	supported, but driver will accommodate the extra 4-byte VLAN tag

   170

 * 	for processing by upper layers.  Tx/Rx Checksum offloading is not

   171

 * 	supported.  Tx Scatter/Gather is not supported.  Jumbo Frames is

   172

 * 	not supported (hardware limitation).

   173

 *

   174

 * 	MagicPacket(tm) WoL support is enabled/disabled via ethtool.

   175

 *

   176

 * 	Thanks to JC (jchapman@katalix.com) for helping with

   177

 * 	testing/troubleshooting the development driver.

   178

 *

   179

 * 	TODO:

   180

 * 	o several entry points race with dev->close

   181

 * 	o check for tx-no-resources/stop Q races with tx clean/wake Q

   182

 *

   183

 *	FIXES:

   184

 * 2005/12/02 - Michael O'Donnell <Michael.ODonnell at stratus dot com>

   185

 *	- Stratus87247: protect MDI control register manipulations

   186

 * 2009/06/01 - Andreas Mohr <andi at lisas dot de>

   187

 *      - add clean lowlevel I/O emulation for cards with MII-lacking PHYs
