Subject: [PATCH 31/33] net/cnxk: add PMD API to retrieve CPT queue statistics
Date: Tue, 10 Sep 2024 14:29:07 +0530 [thread overview]
Message-ID: <20240910085909.1514457-32-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20240910085909.1514457-1-ndabilpuram@marvell.com>
From: Srujana Challa <schalla@marvell.com>
Introduces a new PMD API to obtain CPT queue statistics, including:
- CPT_LF_CTX_ENC_BYTE_CNT - Encrypted byte count on the given queue
- CPT_LF_CTX_ENC_PKT_CNT - Encrypted packet count on the given queue
- CPT_LF_CTX_DEC_BYTE_CNT - Decrypted byte count on the given queue
- CPT_LF_CTX_DEC_PKT_CNT - Decrypted packet count on the given queue
This API enables applications to access CPT queue statistics directly.
