[PATCH net-next v3 0/8] r8152: refactor and extend RTL8157/8159 support

[Chih Kai Hsu <hsu.chih.kai@realtek.com>]

v3:
Rebase on top of latest net-next to resolve merge conflicts.

v2:
- For patch #1, use read_poll_timeout() to replace the manual for-loop polling.
- For patch #2 and #3, rewrite the commit message.

v1:
RTL8157 and RTL8159 have different init, enable, up/down, hw_phy_cfg,
and PHY access sequences from RTL8156.  This series splits the shared
callbacks into per-chip variants and adds the missing RTL8157/8159
functionality: dedicated unload and change_mtu callbacks, TGPHY register
access via phy_read/phy_write pointers in struct rtl_ops, flow control
patch support through rtl_fc_pause_pkt_en(), and UPS support via
r8157_ups_en().
