Subject: [PATCH v4 6/8] net/vmxnet3: advertise RETA size in device info
Date: Thu,  5 May 2022 18:00:17 -0400
Message-ID: <20220505220019.31166-7-pagupta@vmware.com> (raw)
In-Reply-To: <20220505220019.31166-1-pagupta@vmware.com>

Currently the driver assumes that the size of the reta table is
four times the number of Rx queues at multiple places. However,
it sets it to four times the maximum number of queues (4 * 32 = 128)
when it first initializes the device. Change the other uses to use
the stored value, not the assumed default.

Tested, using testpmd, for different hardware version on
ESXi 7.0 Update 2.
