Subject: test/distributor: switch sequence to dynamic mbuf field
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=6e1096939de00871174bc4d2f187f78c8270ca33;p=dpdk.git

test/distributor: switch sequence to dynamic mbuf field

The test used the deprecated mbuf field udata64.
It is moved to a dynamic field in order to allow removal of udata64.
