If so, is there real need for that? Can't we have either some value for max_lro_pktlen, that would indicate PMD to use the default value it prefers? Or probably better to let have a separate function to set max lro size. Then by default PMD will always use its preferred value, and when needed user can change it via special function call.=20 > }; >=20 > struct rte_eth_txmode tx_mode =3D { > diff --git a/doc/guides/testpmd_app_ug/run_app.rst b/doc/guides/testpmd_a= pp_ug/run_app.rst > index 00e0c2a..721f740 100644 > --- a/doc/guides/testpmd_app_ug/run_app.rst > +++ b/doc/guides/testpmd_app_ug/run_app.rst > @@ -112,6 +112,11 @@ The command line options are: >=20 > Set the maximum packet size to N bytes, where N >=3D 64.
