2 - fix handling of timeout (program timer of RC632)
3 - add a timeout tolerance factor that can be user-specified
4 - make sure interrupt mode for timer wait works
7 - fix handling of TX or RX > 0x7f [buffer length in atmel chip?]
13 - implement 'option 2' frame markers
14 - test anticollission (need multiple tags)
17 - implement anticollision
18 - implement all the rest
22 - try to auto-detect 1k/4k
23 - try to distinguish mifare ultralight and mifare classic in/after anticol
26 - implement pps for asymmetric (rx/tx) speeds
29 - add ifdhandler driver
32 - implementation of code for various passive tags
34 - add notion of 'asic implementation' for specifying reader-specific
35 initialization values such as mod_conductance
36 - abstract a read single block / read multiple block API where l2/proto
37 layer can provide multi-block function (e.g. iso15693), which will be
38 emulated in case there only is a single-block function
39 - switch over to use of rfid_buf structure, similar to linux skb. upper
40 layers have sufficient headroom in order to have lower layers add protocol
41 headers in front of a packet
42 - implement software checksumming support. The reader should be able to
43 indicate whether it supports hardware checksum generation / verification.
44 - application software should be able to override hardware csumming on request
45 - implement some auto-calibration mode where the user is requested to leave a
46 single PICC/VICC on the reader and the software iterates through various
47 mod_conductance and bitphase values to see whether it can calibrate to a given
48 [new] card. The resulting calibration values are printed by the program.
