apps: fix default mbuf size
Latest mbuf changes (priv_size addition and related fixes) exposed small problem with testpmd and few other sample apps: when mbuf size is exaclty 2KB or less, that causes ixgbe PMD to select scattered RX even for configs with 'normal' max packet length (max_rx_pkt_len == ETHER_MAX_LEN). To overcome that problem and unify the code, new macro was created to represent recommended minimal buffer length for mbuf. When appropriate, samples are updated to use that macro. Fixes: dfb03bbe2b ("app/testpmd: use standard functions to initialize mbufs and mbuf pool") Signed-off-by: Konstantin Ananyev <konstantin.ananyev@intel.com> Acked-by: Olivier Matz <olivier.matz@6wind.com>
