commit e72bde6b66299602087c8c2350d36a525e75d06e upstream.
Marco reported an error with hfsc: root@Calimero:~# tc qdisc add dev eth0 root handle 1:0 hfsc default 1 Error: Attribute failed policy validation.
Apparently a few implementations pass TCA_OPTIONS as a binary instead of nested attribute, so drop TCA_OPTIONS from the policy.
