Subject: [PATCH 5.4 079/152] octeontx2-af: change (struct qmem)->entry_sz from u8 to u16

From: Eric Dumazet <edumazet@...gle.com>

[ Upstream commit 393415203f5c916b5907e0a7c89f4c2c5a9c5505 ]

We need to increase TSO_HEADER_SIZE from 128 to 256.

Since otx2_sq_init() calls qmem_alloc() with TSO_HEADER_SIZE,
we need to change (struct qmem)->entry_sz to avoid truncation to 0.

Fixes: 7a37245ef23f ("octeontx2-af: NPA block admin queue init")
