net: ethtool: Initialize buffer when querying device channel settings
[ Upstream commit 31a86d137219373c3222ca5f4f912e9a4d8065bb ]
Ethtool channels respond struct was uninitialized when querying device
channel boundaries settings. As a result, unreported fields by the driver
hold garbage. This may cause sending unsupported params to driver.
Fixes: 8bf368620486 ('ethtool: ensure channel counts are within bounds ...')
