You need to re-specify dst with "mask" instead of "spec". You can specify it
as many times you like to update each structure in turn, e.g.:
testpmd> flow create 0 ingress pattern eth dst spec 00:00:00:00:09:00 dst mask
00:00:00:00:ff:ff
If you want to specify both spec and mask at once assuming you want it full,
these commands yield the same result:
testpmd> flow create 0 ingress pattern eth dst fix 00:00:00:00:09:00
testpmd> flow create 0 ingress pattern eth dst spec 00:00:00:00:09:00 dst mask
ff:ff:ff:ff:ff:ff
testpmd> flow create 0 ingress pattern eth dst spec 00:00:00:00:09:00 dst
prefix 48
You are even allowed to change your mind:
testpmd> flow create 0 ingress pattern eth dst fix 00:00:2a:2a:2a:2a dst fix
00:00:00:00:09:00
All these will be properly documented in the v2 patchset. Note, this version
will replace the "fix" keyword with "is" ("fix" made no sense according to
feedback).
