      3c59x: Remove atomic context inside vortex_{set|get}_wol · 84176b7b
      Denis Kirjanov authored
      There is no need to use spinlocks in vortex_{set|get}_wol.
      This also fixes a bug:

      vortex_set_wol protected with a spinlock, but nested  acpi_set_WOL acquires a mutex inside atomic context.
      Ethtool operations are already serialized by RTNL mutex, so it is safe to drop the locks.

      tcp: Prevent overzealous packetization by SWS logic. · 01f83d69
      Alexey Kuznetsov authored
      If peer uses tiny MSS (say, 75 bytes) and similarly tiny advertised
      window, the SWS logic will packetize to half the MSS unnecessarily.
      
      This causes problems with some embedded devices.
      
      However for large MSS devices we do want to half-MSS packetize
      otherwise we never get enough packets into the pipe for things
      like fast retransmit and recovery to work.
      
      Be careful also to handle the case where MSS > window, otherwise
      we'll never send until the probe timer.

      You cannot invoke __smp_call_function_single() unless the
