2.7.4
This patch fixes the missing u64_stats_fetch_begin_irq() while trying to
atomically do 64-bit RX/TX fetch. We did not get any error during test
as our SoC is 64-bit so all of these seq/lock operations results in NOOP.
As such, this seq lock supports has been added for the sake of completion
if this code ever runs on 32-bit platform and we are trying to do 64-bit
stats fetch.
Fixes: 76ad4f0ee747 ("net: hns3: Add support of HNS3 Ethernet Driver for
hip08 SoC")
