use eth_broadcast_addr() to assign broadcast address
Using eth_broadcast_addr() to assign broadcast address instead of copying from an array that contains the all-ones broadcast address Port 78adf574c969c14a470b686af8d6bd7e1dcf142b Port 3b0a4a1bdb0f6348dba797a0fa1cf161f5639ded Port 44c26bec861476f89ac5aee0bb19df128a42543b Link: https://lore.kernel.org/r/20210616081243.2511663-4-yangyingliang@huawei.com
