Subject: [RFC PATCH 16/19] net/ice: fix build with shadow warnings enabled
Date: Thu, 6 Nov 2025 14:09:45 +0000 [thread overview]
Message-ID: <20251106140948.2894678-17-bruce.richardson@intel.com> (raw)
In-Reply-To: <20251106140948.2894678-1-bruce.richardson@intel.com>
The RTE_MIN macro used newly-defined local variables internally, which
means that it had variable shadowing issues when one RTE_MIN call was
used inside another. Fix this for ice driver by using two separate
RTE_MIN calls to have the same effect.
Fixes: 8c03aa5e00f0 ("net/ice: optimize maximum queue number calculation")
