When calling the flow_free() to free the flow, we call many times
(cpu_possible_mask, eg. 128 as default) cpumask_next(). That will
take up our CPU usage if we call the flow_free() frequently.
When we put all packets to userspace via upcall, and OvS will send
them back via netlink to ovs_packet_cmd
In the ovs_flow_stats_update(), we only use the node
var to alloc flow_stats struct. But this is not a
common case, it is unnecessary to call the numa_node_id()
everytime. This patch is not a bugfix, but there maybe
a small increase.

This patch is to remove the typedef sctp_hmac_algo_param_t, and
replace with struct sctp_hmac_algo_param in the places where it's
using this typedef.
It is also to use sizeof(variable) instead of sizeof(type).

Hello,
each time I disconnect my card from AP my dmesg gets flooded like this :
...
ath10k_pci :03:00.0: no channel configured; ignoring frame(s)!
ath10k_warn: 155 callbacks suppressed
Can ath10k_warn() be ath10k_dbg() there ? Maybe this ?
