chelsio: Move the Chelsio drivers

Browse Source 
Moves the drivers for the Chelsio chipsets into
drivers/net/ethernet/chelsio/ and the necessary Kconfig and Makefile
changes.

# Chelsio device configuration

config NET_VENDOR_CHELSIO
bool "Chelsio devices"
depends on PCI || INET
---help---
If you have a network (Ethernet) card belonging to this class, say Y
and read the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
Note that the answer to this question doesn't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about Chelsio devices. If you say Y, you will be asked for
your specific card in the following questions.
if NET_VENDOR_CHELSIO
config CHELSIO_T1
tristate "Chelsio 10Gb Ethernet support"
depends on PCI
select CRC32
select MDIO
---help---
This driver supports Chelsio gigabit and 10-gigabit
Ethernet cards. More information about adapter features and
performance tuning is in <file:Documentation/networking/cxgb.txt>.
For general information about Chelsio and our products, visit
our website at <http://www.chelsio.com>.
For customer support, please visit our customer support page at
<http://www.chelsio.com/support.html>.
Please send feedback to <linux-bugs@chelsio.com>.
To compile this driver as a module, choose M here: the module
will be called cxgb.
config CHELSIO_T1_1G
bool "Chelsio gigabit Ethernet support"
depends on CHELSIO_T1
---help---
Enables support for Chelsio's gigabit Ethernet PCI cards. If you
are using only 10G cards say 'N' here.
config CHELSIO_T3
tristate "Chelsio Communications T3 10Gb Ethernet support"
depends on PCI && INET
select FW_LOADER
select MDIO
---help---
This driver supports Chelsio T3-based gigabit and 10Gb Ethernet
adapters.
For general information about Chelsio and our products, visit
our website at <http://www.chelsio.com>.
For customer support, please visit our customer support page at
<http://www.chelsio.com/support.html>.
Please send feedback to <linux-bugs@chelsio.com>.
To compile this driver as a module, choose M here: the module
will be called cxgb3.

tristate "Chelsio Communications T4 Ethernet support"
depends on PCI
select FW_LOADER
select MDIO
---help---
This driver supports Chelsio T4-based gigabit and 10Gb Ethernet
adapters.
For general information about Chelsio and our products, visit
our website at <http://www.chelsio.com>.
For customer support, please visit our customer support page at
<http://www.chelsio.com/support.html>.
Please send feedback to <linux-bugs@chelsio.com>.
To compile this driver as a module choose M here; the module

tristate "Chelsio Communications T4 Virtual Function Ethernet support"
depends on PCI
---help---
This driver supports Chelsio T4-based gigabit and 10Gb Ethernet
adapters with PCI-E SR-IOV Virtual Functions.
For general information about Chelsio and our products, visit
our website at <http://www.chelsio.com>.

* section 13.1 -- Device Reset.
*
* The PM3393 has three types of components that are
* individually reset:
*
* DRESETB - Digital circuitry
* PL4_ARESETB - PL4 analog circuitry
* XAUI_ARESETB - XAUI bus analog circuitry
*
* Steps to reset PM3393 using RSTB pin:
*
* 1. Assert RSTB pin low ( write 0 )
* 2. Wait at least 1ms to initiate a complete initialization of device.
* 3. Wait until all external clocks and REFSEL are stable.
* 4. Wait minimum of 1ms. (after external clocks and REFEL are stable)
* 5. De-assert RSTB ( write 1 )
* 6. Wait until internal timers to expires after ~14ms.
* - Allows analog clock synthesizer(PL4CSU) to stabilize to
* selected reference frequency before allowing the digital
* portion of the device to operate.
* 7. Wait at least 200us for XAUI interface to stabilize.
* 8. Verify the PM3393 came out of reset successfully.
* Set successful reset flag if everything worked else try again
* a few more times.
