[dpdk-dev] [PATCH] common/sfc_efx/base: fix indication of MAE encap. support

[Ivan Malov]

The indication fields in the MCDI response are individual
bits, but the current code mistakenly compares the larger
dword with 1. This breaks encap. type discovery. Fix that.

Fixes: 891408c45a63 ("common/sfc_efx/base: indicate MAE support for encapsulation")
