[DCCP]: Set TX Queue Length Bounds via Sysctl
Previously the transmit queue was unbounded. This patch: * puts a limit on transmit queue length and sends back EAGAIN if the buffer is full * sets the TX queue length to a sensible default * implements tx buffer sysctls for DCCP Signed-off-by: Ian McDonald <ian.mcdonald@jandi.co.nz> Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
