Commit Message

Andrew Rybchenko June 5, 2022, 9:47 a.m. UTC 
  eth_hw_addr_random() sets address type correctly.

eth_hw_addr_random() is available since Linux v3.4, so
no compat is required.

Also fix the warning:
warning: passing argument 1 of ‘memcpy’ discards ‘const’
qualifier from pointer target type

Variable dev_addr is done const intentionally in Linux v5.17 to
prevent using it directly.

Fixes: ea6b39b5b847 ("kni: remove ethtool support")
