[RFC net-next 1/6] tools: ynl: fix render-max for flags definition

[Lorenzo Bianconi]

Properly manage render-max property for flags definition type
introducing mask value and setting it to (last_element << 1) - 1
instead of adding max value set to last_element + 1

Fixes: be5bea1cc0bf ("net: add basic C code generators for Netlink")

Could you use EnumSet::get_mask instead() ?

I think it also needs to be fixed to actually walk the elements 
and combine the user_value()s rather than count them and assume
there are no gaps.

ack, I will fix it.

Do you mean get_mask()?

Yup, get_mask() predates the ability to control the values of enum
entries individually so while at it we should fix it.

[RFC net-next 2/6] xdp: add xdp_set_features_flag utility routine

[Lorenzo Bianconi]

Introduce xdp_set_features_flag utility routine in order to update
dynamically xdp_features according to the dynamic hw configuration via
ethtool (e.g. changing number of hw rx/tx queues).
Add xdp_clear_features_flag() in order to clear all xdp_feature flag.

[RFC net-next 6/6] net/mlx5e: take into account device reconfiguration for xdp_features flag

[Lorenzo Bianconi]

Take into account LRO and GRO configuration setting device xdp_features
flag. Moreover consider channel rq_wq_type enabling rx scatter-gatter
support in xdp_features flag.
