From: Yevgeny Kliteynik <kliteyn@xxxxxxxxxx> [ Upstream commit 94a3ad6c081381fa9ee523781789802b4ed00faf ] This patch reduces the size of hw_ste_arr_optimized array that is allocated on stack from 640 bytes (5 match STEs + 5 action STES) to 448 bytes (2 match STEs + 5 action STES). This fixes the 'stack guard page was hit' issue, while still fitting majority of the usecases (up to 2 match STEs).
