svn commit: r280430 - head/sys/dev/netmap

Log:
  Make ix_crcstrip a public symbol for the moment;  it probably is not
  the right solution but I will leave it to experts to untangle this
  problem to properly stop the build failures.
  
  At the moment only if_ix.c includes dev/netmap/ixgbe_netmap.h which is
  good as ixgbe_netmap.h defines a couple of (file) static variables--thus
  local to if_ix.c.
  static int ix_crcstrip however now also got checked from ix_txrx.c
  (as an extern) and should not be visible there.  In fact we do see
  powerpc and powerpc64 build failures because of this.  It is unclear
  to me why on other (clang built?) architectures this does not lead
  to a reference of an undefined symbol and similar build breakage.
