[Acx100-devel] [PATCH] WLAN acx100: some optimization/cleanup

[Andreas M. <an...@us...>]

[copying netdev for centralized development]

Hi all,

some updates to acx-20060111:

- add some cache prefetching at critical places, but still unsure whether it
  helps (some rdtscl() testing hasn't shown much yet),
  thus make it configurable
- add recommended cpu_relax() to busy-wait loops
- use "counter % 8" instead of "counter % 5" for easier ASM calculation
- add ACX_IE_HDR__TYPE_LEN define for IE struct header variables used
  everywhere
- reorder struct wlandevice_t for better(??) cache use
- kill superfluous result variable in conv.c
- misc. small cleanup

This patch is rediffed from my modified acx-20060109 tar, NOT compile-tested!
