#. commit 98382f419f32d2c12d021943b87dea555677144b
#. net: Cap number of elements for sendmmsg
#. To limit the amount of time we can spend in sendmmsg, cap the
#. number of elements to UIO_MAXIOV (currently 1024).
#. For error handling an application using sendmmsg needs to retry at
#. the first unsent message, so capping is simpler and requires less
#. application logic than returning EINVAL.
