![]() 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.

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 Signed-off-by: Scott Bardone <sbardone@chelsio.com> Signed-off-by: Christoph Lameter <christoph@lameter.com> Signed-off-by: Andrew Morton <akpm@osdl.org> diff -puN /dev/null Documentation/networking/cxgb.txt |
