Subject: [PATCH 3.17 026/319] stmmac: pci: set default of the filter bins

3.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

[ Upstream commit 1e19e084eae727654052339757ab7f1eaff58bad ]

The commit 3b57de958e2a brought the support for a different amount of the
filter bins, but didn't update the PCI driver accordingly. This patch appends
the default values when the device is enumerated via PCI bus.

Fixes: 3b57de958e2a (net: stmmac: Support devicetree configs for mcast and ucast filter entries)
