ir2603_vlsi-05.diff :
~~~~~~~~~~~~~~~~~~~
<Patch from Martin Diehl>
* correct endianess conversion of hardware exposed fields
* we need to check crc16 of rx frames in SIR-mode
(hardware does this in MIR/FIR modes). Use irda_calc_crc16.
* get rid of BUG'gers - having them in interrupt path isn't fun.
* don't return NET_XMIT_DROP when we drop (dev_kfree_skb_any)
frames. This value is meant to ask for retransmit so we would
corrupt the skb slab.
* locking review, corrections and improvements: particularly focus on speed setting and start_xmit paths, but also reducing time
we are staying with interrupts disabled.
* printk-cleanup: less/better syslog msgs, use IRDA_DEBUG and friends.
* default qos_mtt_bits should be 1ms or longer (0x07), not exactly 1ms
* rename IRENABLE_IREN -> IRENABLE_PHYANDCLOCK
* few minor improvements * compatibility stuff to preserve 2.4 backport path
* it's a pci controller, so we should depend on CONFIG_PCI
* DRIVER_VERSION 0.5
