      Ben Hutchings 提交于
      The driver needs specific PHY and board support code for each SFC4000
      board; there is no point trying to continue if it is missing.
      Currently unsupported boards can trigger an 'oops'.

      sctp: fix to calc the INIT/INIT-ACK chunk length correctly is set · a8170c35
      Wei Yongjun 提交于
      When calculating the INIT/INIT-ACK chunk length, we should not
      only account the length of parameters, but also the parameters
      zero padding length, such as AUTH HMACS parameter and CHUNKS
      parameter. Without the parameters zero padding length we may get
      following oops.

      sctp: avoid irq lock inversion while call sk->sk_data_ready() · 561b1733
      Wei Yongjun 提交于
      sk->sk_data_ready() of sctp socket can be called from both BH and non-BH
      contexts, but the default sk->sk_data_ready(), sock_def_readable(), can
      not be used in this case. Therefore, we have to make a new function
      sctp_data_ready() to grab sk->sk_data_ready() with BH disabling.
