Re: Submission for S2io 10GbE driver

[Christoph Hellwig <hch@infradead.org>]

A bunch of comments:

 - if you want to submit the driver for inclusion please submit a patch against a kernel tree,
   not a tarball.
 - please try to avoid version ifdefs by provoding the newer APIs on older kernels, e.g.:

#ifndef IRQ_RETVAL
#define irqreturn_t                     void
#define IRQ_RETVAL(foo)
#endif

#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,00)
#define free_netdev kfree
#endif

 - your AS_A_MODULE ifdef is bogs - everything under it is fine for a
   non-modular driver, too
 - your XENA_ARCH_64 is not good - just cast 64bit values to
   (unsigned long long) always and use the ll format specifier always.
   You missed a few 64bit arches, btw :)
 - can you get rid of all those BOOL/TRUE/FALSE/SUCCESS/etc.. ifdefs?
 - s2io_driver wants to be converted to C99 initializers (.foo instead of foo:)
 - In Linux comments usually are on the same indentation level as surrounding
   code
 - CONFIGURE_NAPI_SUPPORT should probably become CONFIG_XENA_NAPI or whatever
 - you want to use ethtool_ops instead of the ioctl variant
 - there's lots of non-static symbols in s2io.c - these shouldn't exist in a
   single source-file driver
 - you can't return -ENOMEM from the isr - just IRQ_HANDLED or IRQ_NONE
 - having the RCS log at the end of the source files looks ... odd
