[PATCH 0/4] net/tap: minor cleanups

[Stephen Hemminger]

These are some minor things in tap device that can be easily fixed.
Not urgent can wait until 25.03 release but submitting now for review.

Stephen Hemminger (4):
  net/tap: replace rte_memcpy
  net/tap: rename struct nlmsg to tap_nlmsg
  net/tap: do not use opaque parameter in convert
  net/tap: do not use rte_malloc for process private data

[PATCH 1/4] net/tap: replace rte_memcpy

[Stephen Hemminger]

There is no point in using rte_memcpy to copy Ethernet addresses.
Use rte_ether_addr_copy() instead.

[PATCH 2/4] net/tap: rename struct nlmsg to tap_nlmsg

[Stephen Hemminger]

The struct netlink message structure is part of the internal
TAP device API, not the netlink API itself. Use tap_ prefix
to avoid any confusion with nlmsghdr from netlink.h

[PATCH 3/4] net/tap: do not use opaque parameter in convert

The function to convert from internal representation to
netlink was using a void pointer when both caller and callee
were using same structure.

[PATCH 4/4] net/tap: do not use rte_malloc for process private data

[Stephen Hemminger]

The process private data is local to the process and does not
have to come from global shared memory. Using malloc() gets more
coverage with tools and has better caching.
