tst_netload function uses $TST_TMPDIR therefore requires
TST_NEEDS_TMPDIR=1. It's better to tell user the reason, as current
error message was a bit misleading:

dccp_ipsec 1 TINFO: run server 'netstress -T dccp -R 500000 -B '
netstress: option requires an argument -- 'B'
-h       Prints this help
-i n     Execute test n times
-I x     Execute test for n seconds
-C ARG   Run child process with ARG arguments (used internally)
-f       Use TFO API, default is old API
-F       TCP_FASTOPEN_CONNECT socket option and standard API
-t x     Set tcp_fastopen value
-S x     Source address to bind
-g x     x - server port
-b x     x - low latency busy poll timeout
-T x     tcp (default), udp, dccp, sctp
-z       enable SO_ZEROCOPY

Client:
-H x     Server name or IP address
-l       Become client, default is server
-a x     Number of clients running in parallel
-r x     Number of client requests
-n x     Client message size
-N x     Server message size
-m x     Reply timeout in microsec.
-d x     x is a path to file where result is saved
-A x     x max payload length (generated randomly)

Server:
-R x     x requests after which conn.closed
-q x     x - TFO queue
-B x     run in background, x - process directory
tst_test.c:492: BROK: Invalid option
dccp_ipsec 1 TFAIL: server failed
