Subject: [dpdk-stable] [PATCH 02/20] net/ena/base: specify operations of rte_delay
Date: Thu, 17 Sep 2020 07:30:17 +0200
Message-ID: <> (raw)
In-Reply-To: <>

ENA_MSLEEP() and ENA_UDELAY() were expecting different behavior - the
first one is expecting driver to sleep, while the other, to busy wait.

For both cases, the rte_delay_(u|m)s() function was used, which could
be either sleep or block, depending on the configuration.

To make the macros valid, the operations should be specified directly.
Because of that, the rte_delay_us_sleep() and rte_delay_us_block() are
now being used.

Fixes: 9ba7981ec992 ("ena: add communication layer for DPDK")
