[dpdk-stable] [PATCH] net/ice: fix queue bind MSI-X interrupt error

[taox.zhu@intel.com]

From: Zhu Tao <taox.zhu@intel.com>

To bind a queue to an MSI-X interrupt, need to set some register.
The register consists of many parts, each of which has several
bits; therefore, the shift operator '<<' was used; so the operator
'<' in the code should be '<<'.

Old code adds 1 on even MSI-X interrupt vector index used by queue,
resulting in interrupt mapping error.

Fixes: 65dfc889d8 ("net/ice: support Rx queue interruption")
