Subject: [PATCH] net: dsa: qca8k: fix an endian bug in
|
|
qca8k_get_ethtool_stats()
|
|
|
|
The "hi" variable is a u64 but the qca8k_read() writes to the top 32
|
|
bits of it. That will work on little endian systems but it's a bit
|
|
subtle. It's cleaner to make declare "hi" as a u32. We will still need
|
|
to cast it when we shift it later on in the function but that's fine.
|
|
