      sctp: Add support to per-association statistics via a new SCTP_GET_ASSOC_STATS call · 196d6759
      Michele Baldessari authored
      The current SCTP stack is lacking a mechanism to have per association
      statistics. This is an implementation modeled after OpenSolaris'
      SCTP_GET_ASSOC_STATS.
      
      Userspace part will follow on lksctp if/when there is a general ACK on
      this.
      V4:
      - Move ipackets++ before q->immediate.func() for consistency reasons
      - Move sctp_max_rto() at the end of sctp_transport_update_rto() to avoid
        returning bogus RTO values
      - return asoc->rto_min when max_obs_rto value has not changed
      
      V3:
      - Increase ictrlchunks in sctp_assoc_bh_rcv() as well
      - Move ipackets++ to sctp_inq_push()
      - return 0 when no rto updates took place since the last call
      
      V2:
      - Implement partial retrieval of stat struct to cope for future expansion
      - Kill the rtxpackets counter as it cannot be precise anyway
      - Rename outseqtsns to outofseqtsns to make it clearer that these are out
        of sequence unexpected TSNs
      - Move asoc->ipackets++ under a lock to avoid potential miscounts
      - Fold asoc->opackets++ into the already existing asoc check
      - Kill unneeded (q->asoc) test when increasing rtxchunks
      - Do not count octrlchunks if sending failed (SCTP_XMIT_OK != 0)
      - Don't count SHUTDOWNs as SACKs
      - Move SCTP_GET_ASSOC_STATS to the private space API
      - Adjust the len check in sctp_getsockopt_assoc_stats() to allow for
        future struct growth
      - Move association statistics in their own struct
      - Update idupchunks when we send a SACK with dup TSNs
      - return min_rto in max_rto when RTO has not changed. Also return the
        transport when max_rto last changed.

      irda: ep7211-sir: Convert to platform_diver · 96070ae4
      Alexander Shiyan authored
      This patch converts ep7211-sir driver to platform_driver.
      Since driver can be used not only for EP7211 CPU, function names
      was be renamed to generic clps711x...
