[PATCH net] Subject: [PATCH] octeontx2-af: fix TX scheduler queue index mask for 2K schedulers

[kmahammadraf]

From: Satha Rao <skoteshwar@xxxxxxxxxxx>

In CN20K, the maximum number of TX schedulers per layer increased from
1K to 2K, so the scheduler queue index field is now 11 bits wide.

Update the TX scheduler masks used for mailbox/config register access:

Increase TXSCHQ_IDX_MASK from 10-bit to 11-bit
Expand NIX_TX_SCHQ_MASK to include bit 26
