2008-04-25[netdrvr] atlx: code movement: move atl1 parameter parsingChris Snook
Move some code from atlx.c to atl1.c to prevent build conflict with the upcoming atl2 code. No changes, just movement. Signed-off-by: Chris Snook <csnook@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-04-25atlx: remove flash vendor parameterChris Snook
There's no good reason to manually set the flash vendor in a module parameter, outside of an Atheros hardware lab. Remove it, so nobody accidentally bricks their board using it incorrectly. Signed-off-by: Chris Snook <csnook@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-03-17atl1: reduce forward declarationsJay Cliburn
Rearrange functions to allow removal of some forward declarations. Make certain global functions static along the way. Signed-off-by: Jay Cliburn <jacliburn@bellsouth.net> Acked-by: Chris Snook <csnook@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-03-17atl1: make functions staticJay Cliburn
Make needlessly global functions static. In a couple of cases this requires removing forward declarations and reordering functions. Signed-off-by: Jay Cliburn <jacliburn@bellsouth.net> Acked-by: Chris Snook <csnook@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-03-17atl1: print debug info if rrd errorJay Cliburn
Add some debug printks if we encounter a potentially bad receive return descriptor. Signed-off-by: Jay Cliburn <jacliburn@bellsouth.net> Acked-by: Chris Snook <csnook@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-03-17atl1: use netif_msgJay Cliburn
Use netif_msg_* for console messages emitted by the driver. Add a parameter to allow control of messaging at driver startup, and also add the ability to control it with ethtool.

2008-03-17atl1: use csum_startJay Cliburn
Use skb->csum_start for tx checksum offload preparation. Also swap the variables css and cso so they hold the intended values of csum start and offset, respectively.

2008-03-17atl1: simplify tx packet descriptorJay Cliburn
The transmit packet descriptor consists of four 32-bit words, with word 3 upper bits overloaded depending upon the condition of its bits 3 and 4. The driver currently duplicates all word 2 and some word 3 register bit definitions unnecessarily and also uses a set of nested structures in its definition of the TPD without good cause. This patch adds a lengthy comment describing the TPD, eliminates duplicate TPD bit definitions, and simplifies the TPD structure itself. It also expands the TSO check to correctly handle custom checksum versus TSO processing using the revised TPD definitions. Finally, shorten some variable names in the transmit processing path to reduce line lengths, rename some variables to better describe their purpose (e.g., nseg versus m), and add a comment or two to better describe what the code is doing.

2008-03-17atl1: add ethtool register dumpJay Cliburn
Add the ethtool register dump option to the atl1 driver. Signed-off-by: Jay Cliburn <jacliburn@bellsouth.net> Acked-by: Chris Snook <csnook@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-03-17atl1: fix broken TSOJay Cliburn
The L1 tx packet descriptor expects TCP Header Length to be expressed as a number of 32-bit dwords. The atl1 driver uses tcp_hdrlen() to populate the field, but tcp_hdrlen() returns the header length in bytes, not in dwords. Add a shift to convert tcp_hdrlen() to dwords when we write it to the tpd. Also, some of our bit assignments are made to the wrong tpd words. Change those to the correct words. Finally, since all this fixes TSO, enable TSO by default.

2008-03-17atl1: move common functions to atlx filesJay Cliburn
The future atl2 driver and the existing atl1 driver can share certain functions and definitions. Move these shareable functions and definitions out of atl1-specific files and into atlx.c and atlx.h. Some transitory hackery will be present until atl2 is merged. Reduce the number of source files by moving ethtool, hw, and param functions from separate files into atl1_main.c, then rename it to just atl1.c. Move all atl1-specific definitions from atl1_hw.h to atl1.h. Finally, clean up to make checkpatch.pl happy.

2008-03-17atl1: relocate atl1 driver to /drivers/net/atlxJay Cliburn
In preparation for a future Atheros L2 NIC driver (called atl2), relocate the atl1 driver into a new /drivers/net/atlx directory that will ultimately be shared with the future atl2 driver.
