[PATCH] A new 10GB Ethernet Driver by Chelsio Communications

A Linux driver for the Chelsio 10Gb Ethernet Network Controller by Chelsio
(http://www.chelsio.com).  This driver supports the Chelsio N210 NIC and is
backward compatible with the Chelsio N110 model 10Gb NICs.  It supports
AMD64, EM64T and x86 systems.

Adrian said:

- my3126.c is unused (because t1_my3126_ops isn't used anywhere)
- what are the EXTRA_CFLAGS in drivers/net/chelsio/Makefile for?
- $(cxgb-y) in drivers/net/chelsio/Makefile seems to be unneeded
- completely unused global functions:
  - espi.c: t1_espi_get_intr_counts
  - sge.c: t1_sge_get_intr_counts
- the following functions can be made static:
  - sge.c: t1_espi_workaround
  - sge.c: t1_sge_tx
  - subr.c: __t1_tpi_read
  - subr.c: __t1_tpi_write
  - subr.c: t1_wait_op_done

shemminger said:

The performance recommendations in cxgb.txt are common to all fast devices,
and should be in one file rather than just for this device. I would rather
see ip-sysctl.txt updated or a new file on tuning recommendations started.
Some of them have consequences that aren't documented well.
For example, turning off TCP timestamps risks data corruption from sequence wrap.

A new driver shouldn't need so may #ifdef's unless you want to putit on older
vendor versions of 2.4

Some accessor and wrapper functions like:
        t1_pci_read_config_4
        adapter_name
        t1_malloc
are just annoying noise.

Why have useless dead code like:

/* Interrupt handler */
+static int pm3393_interrupt_handler(struct cmac *cmac)
+{
+       u32 master_intr_status;
+/*
+    1. Read master interrupt register.
+    2. Read BLOCK's interrupt status registers.
+    3. Handle BLOCK interrupts.
+*/

Jeff said:

step 1:  kill all the OS wrappers.

 And do you really need hooks for multiple MACs, when only one MAC is
 really supported?  Typically these hooks are at a higher level anyway --
 struct net_device.

From: Christoph Lameter <christoph@lameter

Driver modified as suggested by Pekka Enberg, Stephen Hemminger and Andrian
Bunk.  Reduces the size of the driver to ~260k.

- clean up tabs
- removed my3126.c
- removed 85% of suni1x10gexp_regs.h
- removed 80% of regs.h
- removed various calls, renamed variables/functions.
- removed system specific and other wrappers (usleep, msleep)
- removed dead code
- dropped redundant casts in osdep.h
- dropped redundant check of kfree
- dropped weird code (MODVERSIONS stuff)
- reduced number of #ifdefs
- use kcalloc now instead of kmalloc
- Add information about known issues with the driver
- Add information about authors

/* The following steps are required to properly reset

* PM3393 datasheet (Issue 2: November 2002)
* 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.
