Subject: [PATCH 0/2] net: support bgmac with B50212E B1 PHY

From: Rafał Miłecki <rafal@...ecki.pl>

I got a report that a board with BCM47189 SoC and B50212E B1 PHY doesn't
work well some devices as there is massive ping loss. After analyzing
PHY state it has appeared that is runs in slave mode and doesn't auto
switch to master properly when needed.

This patchset fixes this by:
1) Adding new flag support to the PHY driver for setting master mode
2) Modifying bgmac to request master mode for reported hardware

Rafał Miłecki (2):
  net: phy: broadcom: support new device flag for setting master mode
  net: bgmac: enable master mode for BCM54210E and B50212E PHYs
