Merge branch 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6
* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6: [IRDA] irda_nl_get_mode: always results in failure [PPP]: Fix output buffer size in ppp_decompress_frame(). [IRDA]: Avoid a label defined but not used warning in irda_init() [IPV6]: Fix kernel panic while send SCTP data with IP fragments [SNAP]: Check packet length before reading [DCCP]: Allocation in atomic context
